The worldwide game has made it tough to compare managers from different continents.
With the quality of competition much higher in Spain than, for example, Saudi Arabia, how do we differentiate between the different achievements and varying trophy cabinets each coach can boast?
We developed a simple metric system that converts trophy wins into points, and the top managers, by trophy haul, became clear.
The shortlist started out 81-strong—featuring the likes of Bruce Arena, Artur Jorge and Abel Braga—and was whittled down to 50.
The metric ranks different competitions in order of their level of prestige, number of clubs involved and competitive playing level. Winning the FIFA World Cup scores you a colossal 10, a major domestic league four points and the Charity Shield a paltry 0.5.
Any club or national achievement is counted, while individual awards are not. If you see a "T" before the rank, it means the scores are level and the players are tied.
Dick Advocaat is one of a number of coaches who've spread their wings in the football management world, taking in every possible opportunity no matter where the location may be.
He's tried Russia, Netherlands, South Korea, Belgium, Scotland and more in attempt to secure more trophies, and he's landed top honours at Rangers, Zenit St Petersburg and PSV Eindhoven.
He recently confirmed his retirement from the game.
In polar opposite fashion to Dick Advocaat, Stan Cullis accrued all of his honours at one club: Wolverhampton Wanderers.
At 31 years of age, he presided over the club's most successful spell ever, landing three English Premier League titles (named First Division at the time) and two FA Cups.

He never tasted European success, but he did possess an impressive knack for winning the top domestic trophy available in any given league.

He was also responsible for a Wolfsburg Bundesliga win in 2009, boasting a formidable strike duo of Edin Dzeko and Grafite.
Muricy Ramalho is another talented head coach who has floated between Brazilian clubs and enjoyed success in various regions of the country.
His best spell came in charge of Sao Paulo, where he won the Brasileiro Serie A title three seasons in a row. After spells at Fluminense and Palmeiras, he took charge of Santos, where he managed the prodigious talent of Neymar.
In 2011, he delivered the ultimate prize: the Copa Libertadores.
Oleg Romantsev is hardly the first name on the lips when it comes to discussing the world's greatest, but the sheer amount of titles he won in his native Russia enables him to qualify under our metric.
He won the Russian Premier League an astonishing eight times with Spartak Moscow, giving the capital club unrivaled dominance in a growing competition.
An assortment of domestic trinkets and cups followed.
Rangers and Celtic have enjoyed hugely dominant spells over Scottish football since its inception, and Scott Symon is the first of several who feature thanks largely due to their control of either club.

Oddly enough, after landing the Cup Winners' Cup in 1967, he was sacked.
Fresh memories of Kenny Dalglish are far from positive, and it's easy to forget why his nickname deservedly remains "King Kenny."
After 13 wonderful years as a player at Liverpool, he took the reins of the club and led them to three First Division titles, two FA Cups and four Charity Shields.
He went on to win the Premier League with Blackburn Rovers in 1995, fostering one of the finest strike partnerships England had ever witnessed in Alan Shearer and Chris Sutton.

Not one to stick to the day in, day out regime of club management, Mario Zagallo tried his hand on the international scene after winning two FIFA World Cups as a player.

His pressing methods have really caught on.
Bela Guttman's impact on Benfica was so severe, the locals believe he left a curse lingering over the club after he departed.
His two European Cup wins with the Eagles represent the true highlight of an illustrious career, changing the face of modern football and developing the game from a tactical standpoint.
Since his departure, Benfica have lost an astonishing amount of finals. Seasons such as the one just gone, in which the side lost three cup finals, do nothing to calm the fears of the curse being real.
Hounded out of Manchester City, Roberto Mancini will know he did a good job in a high-pressure situation and leaves with his head held high.
His outrageous domestic success in his native Italy assures him of a place in the 50 most successful managers of all time; Four Coppa Italia wins and three Serie A titles, added to his titles in England, make for a cosy trophy cabinet.
The Italian has indicated his willingness to return to management to the Associated Press, via Mail.com, potentially eyeing a 2014 FIFA World Cup job.
Aime Jacquet guided his nation to a home FIFA World Cup win—a feat which cannot be understated considering the pressures and expectations involved.

Even better, he managed to rinse an impressive Brazil side in the World Cup final 3-0 with the much-maligned Stephane Guivarc'h on the pitch.
Luis Alonso Perez—or Lula, for short—is one of Brazil's most successful domestic managers.
He won the Tacas Brasil an incredible five times, two Copa Libertadores and seven Campeonatos state championships for his beloved Santos, making them a dominant force from 1954 to 1966.
He won one last state championship for Corinthians before retiring.
The fact that Sven-Goran Eriksson has taken jobs at the likes of Notts County and Leicester takes away from his brilliant beginnings as a manager.

He's currently at Guangzhou R&F in China.
Raymond Goethals is the most successful Belgian manager ever to have graced the managerial game, cutting his teeth with Anderlecht and Standard Liege before moving onto Europe's big guns.

At the culmination of the 1992-93 season, Goethals led L'OM to victory in the UEFA Champions League final, beating Milan 1-0 in Munich.
Rafa Benitez attracts a curious amount of hatred and mockery considering the amount of titles he's won and the clubs he's managed.
He's one of the few men who have been able to break up the Spanish Real Madrid-Barcelona duopoly in La Liga, while he won the UEFA Champions League with Liverpool in 2005.
Even at Chelsea, where he was booed vociferously by the home support, he won the Europa League.
From one Chelsea interim manager to another, then.
Guus Hiddink made his name in the Netherlands by winning six Eredivisie titles and four domestic cups, but most impressive was his European Cup triumph in 1988.
He took South Korea to dizzying heights in the 2002 FIFA World Cup, then managed Australia and Russia in final attempts to succeed on the international stage,
He's currently in charge of the mega-rich Anzhi Makhachkala.

He lead the Gers to 10 Scottish Premier League titles and eight total domestic cups. He now works on the board of the club as chairman, fighting to get the club back to the top tier.
He took in a spell at Everton, and also served as assistant to Sir Alex Ferguson in 2004.
Otto Rehhagel was the defensive genius behind Greece's unthinkable Euro 2004 win in Portugal.

His last job was in charge of Hertha Berlin.
Luis Cubilla was the mastermind behind a dominant Olimpia side between 1979 and 1999.

Brian Clough is a truly famous figure in English football.

As the animosity toward Arsene Wenger grows and grows, it becomes easy to forget all of the great work he's done at Arsenal over the last decade-and-a-half.
Coming in fresh from successes at Monaco, he's recruited well, stuck to his principles and made the football club a lot of money.
With new money coming in, the trophy drought won't go on much longer.
Rinus Michels has left one of the biggest stylistic footprints on the game.
His work in the Netherlands lead to an impressive Euro 1988 victory over the Soviet Union, utilising the perfect mixture of free-flowing, pass-and-move football and a ruthless securing of results.
He went on to inspire many players to become fantastic coaches—á la Bobby Robson—and tasted futher success in Spain and Germany.
Vanderlei Luxemburgo has been a huge success in the Brazilian domestic leagues, winning Serie A and state championship titles with ease for several different clubs.
His cameo at Real Madrid—in which he tried to bring the magical quadrilateral formation to Europe—failed, but he bounced back with ease at Santos and continues to impress.
The 1999 Copa America win with Brazil is the highlight of his C.V.
Luiz Felipe Scolari's big achievement in his career remains the FIFA World Cup triumph with Brazil.

Johan Cruyff shone as a player, scoring impossible goals and carrying both club and country in the depths of major international tournaments.
Turning manager, he revolutionised the game, and the framework he built at Barcelona can be found bearing fruits in the forms of Thiago Alcantara, Pedro and Sergio Busquets.
Cules have a lot to thank for him for.
Sir Matt Busby led a Manchester United team to five First Division titles, two FA Cups and even a European Cup.
He did so in tragic circumstances following the Munich Air disaster, and every British kid knows the meaning of the phrase "the Busby Babes."
Busby famously declined "managing paradise" in the form of Real Madrid, rejecting the club's advances and suggesting Manchester was "his heaven."
With the Ligue 1 title secured, Carlo Ancelotti has now sampled title success in three different countries.

Mircea Lucescu remains one of the most underrated and understated coaches in the game.
There's no denying that his club, Shakhtar Donetsk, play some of the best football in Europe. Brendan Rodgers, among others, is seeking to replicate his advanced, entertaining system on the pitch by bringing in some of the Hirnyky's players.
Lucescu has always been ahead of the game and isn't afraid to try something innovative to get results.
Pep Guardiola has the hardest job in football next season as he succeeds Jupp Heynckes at Bayern Munich, but don't doubt his C.V. for one second.
At 42 years of age he's won more than most could dream of, including two UEFA Champions Leagues, three La Ligas and two Copa del Reys with Barcelona.
He played for Barca, he managed Barca; it will be interesting to see him tackle a club not made of his own flesh and blood.
Louis van Gaal is working wonders with the Netherlands, sculpting a great back line and utilising all the superb youth products moving into the prime of their careers.
The Dutch needed a world-class manager to guide them into the 2014 World Cup after Bert van Marwijk's disastrous Euro 2012, and van Gaal is the perfect man to do it.
Victory in Brazil would surpass all of his achievements so far—including winning the UEFA Champions League with Ajax.

His last adventure, in charge of England, ended poorly, but PSG will enter the new season clear favourites to win Ligue 1.
There are those who claim Vincente Del Bosque has the easiest job in football, but don't be fooled by his calm, complacent nature on the touchline.
Spain went stale and dragged themselves to victory at Euro 2012, but their showings at the 2013 Confederations Cup have been truly electric.
La Roja have evolved, improved and changed to stay on top. It's what's made Del Bosque such a great coach throughout his career.

They conquered "La Grande Inter" in the UEFA Champions League final in 1967, boasting electric players such as club legend Jimmy Johnstone and Stevie Chalmers.
Ten Scottish league titles, eight Scottish cups and six Scottish league cups ensured they were the dominant domestic force across the 1960s and 1970s.

A painting of him sits in the Glaswegian side's board room, a tribute to his influence on their history.
Helenio Herrera's methods have been questioned, but his results were ruthless and effective.
He developed the infamous Italian defensive system known as catenaccio, drilling his side to withstand any and all attacks.
He won Internazionale the European Cup in 1964 and 1965, brought three Scudettos to the San Siro and excelled for Barcelona and Atletico Madrid too.
Udo Lattek led Bayern Munich through an extremely dominant period in the late 20th century.
Between domestic cup and title success with the Bavarian outfit, he hauled in trophies with Barcelona and Borussia Moenchengladbach, too.
The German, now 78 years of age, appears infrequently as a sports broadcaster and pundit.
Willie Maley won 16 Scottish titles with Celtic in a truly inspiring tenure at the football club.
He added 14 Scottish Cups and 14 Glasgow Cups to his C.V. while he was at it, making for a trophy haul-high in terms of pure numbers on this list.
Maley is the most successful man ever to manage in Scotland.
It doesn't matter if he's happy, special or simply downright disgruntled, Jose Mourinho wins trophies.
As Real Madrid manager, he stopped Barcelona in their tracks just as they were starting to appear unbeatable, and who can forget his historic treble at Internazionale?
Nine years ago it all started in FC Porto, winning the double. Now, on his return to Chelsea, he's looking to win the UEFA Champions League with a third club.
As manager of Switzerland, Ottmar Hitzfeld gets little attention.
Few have dominated Germany in a way he has, though, recording seven Bundesliga titles, countless cups and even a Champions League win with Bayern Munich.
He's achieved club-level success with Swiss sides, too, and clearly has a penchant for the country.
Apart from his fantastic quotes, Bob Paisley was also rather famous for his impressive tenure as Liverpool manager in the 1970s.

He was awarded an OBE for his service to English football in 1983.
Two of Real Madrid's impressive nine European Cup successes can be attributed to one man: Miguel Munoz.

Munoz sadly passed away in Madrid in 1990, but he is still a true hero in the capital.
Giovanni Trapattoni has seen it all, done it all.
His trophy haul with Juventus was beyond absurd, and he's gone on to impress in Austria, Portugal, and Germany too.
Current boss of Republic of Ireland, "Trap" knows it will be a miracle if he is able to extract any major international trophies out of the Boys in Green.
The greatest manager of all time in almost every aspect of the game is Sir Alex Ferguson.
Football will do well to find another like him—and another club willing to display patience like Manchester United did—and Fergie sweeps our list with ease.
A fantastic man-manager and student of the game, his trophy haul will take some beating.
