Managers are often the most criticized members in football communities.
This happens for a variety of reasons: they are largely responsible for choosing players for the squad's first team, for selecting players to play in each match and for the strategies and substitutions used.
These reasons make the manager accountable for the actions of their squad. If the team performs well, the manager continues to take charge of the club.
If not, the manager gets sacked, a feature which has become more common in today's world where good results are required immediately.
The bosses who manage to avoid the sack year after year are among the best managers on the planet. These managers are considered to be the leading managers in the world because they are able to get the most out of their players, no matter how talented they are.
Here are 10 managers who know how to get the most out of their players.
Borussia Dortmund have reached their greatest heights since the late 1990s under the leadership of Jurgen Klopp.
Klopp, who joined Dortmund in 2008, managed a club of young and inexperienced players to consecutive Bundesliga titles.
Last year's campaign saw Dortmund claim 81 points, the highest point total achieved by a club in Bundesliga history. The 2011-12 season also saw Dortmund claim the DFB-Pokal to complete the first double in the history of the club.
These young players allowed Dortmund to finish first in their Champions League group this season alongside European giants Manchester City and Real Madrid.
Although their chances to win the Bundesliga are small this year, Klopp has made these young German players into one of the best sides in Europe.
For a club with limited finances like Everton, it takes a smart manager to elevate them to be among the best sides in England.
David Moyes has done this regularly since his appointment in 2002. Thanks to smart moves, the Scot brought in talented players like Marouane Fellaini, Mikel Arteta, Tim Cahill and Tim Howard in relatively inexpensive moves.
The squad Moyes has assembled has elevated Everton to contend for the fourth and final Champions League berth this season.
Athletic Bilbao may be struggling to avoid relegation this season. The main reason why they have struggled is due to their losses following an outstanding year under the leadership of Marcelo Bielsa.
Bielsa's managerial style causes normally unremarkable players to rise to stardom. However, it could also cause players to struggle due to the tremendous physical demand it provides.
When he managed Chile, Bielsa brought Chile to their first World Cup since 1998 and won their first games since the 1962 World Cup.
Thanks to Bielsa's style, players like Alexis Sanchez and Javi Martinez have risen to stardom.
Arsenal fans may have complaints about Arsene Wenger's failure to capture any major trophies in recent years. However, they should not complain about the consistency they have achieved under the controversial French manager.
During Wenger's 16 years managing the Gunners, they have never finished lower than fourth, a feat only Manchester United can replicate in the Premier League.
What makes Wenger's run even more remarkable is how he does this with one of the youngest squads in the Premier League on a regular basis.
Whenever Wenger replaces one of his key players, he finds ways to replicate their production through shrewd transfers and tactical changes.
Jose Mourinho may have been handed talented squads with each of his managerial positions, however the Portuguese boss has brought these squads to league titles within years of his appointments, along with European success.
This should be expected considering the talent Mourinho had available. However, Chelsea, Inter Milan and Real Madrid were all relatively unsuccessful in European competition in the years before he took over them.
He has successfully managed superstars to work together to win titles, along with implementing young players in a way which has brought his clubs success.
Vicente del Bosque was an outstanding manager with Real Madrid, where he won two European Cups in a three-year span.
However, his most famous work is with the Spanish national team, a side that historically has been divided, hence causing failure in most international competitions.
Since taking over the squad in 2008, Del Bosque has made Spain into arguably the most successful international side ever with a World Cup in 2010 and a European Championship in 2012.
By producing a stronger team chemistry, Del Bosque has allowed Spain to reach the heights it always failed to reach.
Over the past decade, there have been few managers who can claim the domestic success Manuel Pellegrini has achieved in La Liga.
Pellegrini brought Villarreal into the Champions League fold, which included an unlikely spot in the 2006 semifinals for the Yellow Submarines. He also brought the small Spanish side to an unlikely second-place spot in the league.
He managed Real Madrid to a team-record 96 points in a season in 2009-10 before moving to Malaga. With the financially stricken side, he has brought them to the Champions League knockout stage for the first time in their history.
Over the past 15 years, Guus Hiddink has brought multiple clubs and national teams to unprecedented heights by managing contrasting personalities and wild expectations.
Hiddink has brought three international sides to the semifinals in major tournaments (Netherlands 1998, South Korea 2002 and Russia in 2008.
He nearly brought Chelsea to a Champions League final in 2009 and almost forced extra time against world champion Italy during the 2006 World Cup.
Hiddink's style and his strong approach with his squad has elevated each major side he has managed.
Joachim Low has managed Germany to consecutive spots in both the 2010 World Cup and 2012 European Cup semifinals despite having the youngest squad in each respective tournament.
Low has done this by integrating a mostly young squad with key veterans like Miroslov Klose and Philipp Lahm, which has worked wonders.
The coaching philosophy used by Low, along with revolutionary training methods, have made Germany a favorite to win next year's World Cup.
Sir Alex Ferguson has managed Manchester United to unprecedented heights over the last 26 years.
Despite having contrasting personalities and some of the greatest players in the world, Ferguson has successfully brought together these players to success.
When he has had to deal with players who bring a negative value to United, he sells them. He has continued to keep players like Ryan Giggs and Paul Scholes to keep a veteran presence.
Fergie also understands his squad in a way that allows all of his players to succeed. This knowledge of his squad allows the Scot to always remain competitive with the same players every year. It also allows many of his players to stay on the squad for decades.
