A gift to Manchester City having qualified for the UEFA Champions League, manager Roberto Mancini and owner Sheikh Mansour have landed the perfect signing in £38 million striker Sergio Aguero.
City's top transfer target Aguero, who is the sixth most expensive player in world football history, could well be that vital weapon in the Citizens' quest for silverware, even if Carlos Tevez leaves.
Having wanted out of Atletico Madrid ever since the La Liga season ended, Kun Aguero couldn't hide his delight at joining Man City, telling SkySports, "I'd always wanted to play in the Premier League. [Manchester City] is a good club and it felt right."
And indeed for both the Argentina international and the Eastlands club, it's a transfer that ticks all the right boxes.
For boss Roberto Mancini, Aguero's signing is the piece of the jigsaw that can take his team to new levels.
Besides the talismanic Carlos Tevez, City don't have a striker who is a proven prolific goalscorer. Rather, most of their forwards have been players who have excelled for one or two seasons, become Europe's hottest property, and have been snapped by the Blues to steal a march on their domestic and European rivals.
Mario Balotelli is yet to score in double figures in a league season, while Edin Dzeko has only scored over 20 goals in two of the 10 seasons he's been a professional footballer. As for the probably outgoing Emmanuel Adebayor, only once in 11 seasons as he scored more than 20 goals, while Roque Santa Cruz and Craig Bellamy have never scored more than 20 goals in a season.
And considering Manchester City only scored 60 goals in the Premier League last season—nine fewer than Chelsea, 12 fewer than Arsenal and 18 fewer than Manchester United—a proven prolific goalscorer is exactly what the doctor ordered at Eastlands.
So step forward Sergio "Kun" Aguero, who has scored more than 20 goals in each of the past four seasons for Atletico Madrid, as well as chipping in with a big number of assists (34 in that period).
Not only will Kun add a new, improved goal threat to City's front line, but his arrival could well improve his teammates' games quite considerably.
If Tevez stays, either Balotelli or Dzeko or both will inevitably find themselves relegated to the bench, especially if Mancini, as predicted, doesn't make his side's football more attacking and "sexy" with a possible 4-3-3 formation.
And with it highly unlikely a £25 million striker will be content with taking up a substitute's role throughout the season, competition for places in that Manchester City lineup will rocket to sky-high levels, making Mancini's dream as a manager a reality.
Competition for places makes every player strive to hit the top of their game, and when there's four or five strikers all doing that, it's nothing but good for the team, both on and off the pitch.
And if Carlos Tevez leaves—which could happen with Inter Milan reportedly seeking a £40 million deal—there will be no sweat for Mancini because Aguero will be the man to fill his boots, and who better to replace him than the man who is considered Argentina's Romario?
If there's any player who can replace Tevez and become what Lionel Messi is to FC Barcelona, both in the dressing room and on the pitch, it's Kun Aguero.
A player who has the undoubted talent to lift City to new heights on the pitch, Aguero's stocky, Tevez-like build, great burst of pace and uncanny ability to get a shot away despite being heavily closed down (something which foreign strikers hardly ever get used to in England) gives him all the attributes needed to a big Premier League success.
And off the pitch, the kid from Quilmes has already said all the right things to boost his chances of becoming a big favourite in the dressing room.
After his first day of training, he stated, "I'm very happy to be here. I enjoyed my time with my colleagues today. I am just looking forward to start playing for my new club."
He then added, "I think we have great players and a great team. I am playing at one of the best English teams at the moment and there are many things that can be achieved. We can win many titles and hopefully it will be a top year for us."
Albeit slightly generic, his comments and his apparent attitude in training at Carrington on Friday give all the signs that this a player who can easily become a success not just on the pitch, but also in the dressing room, which is equally as important.
So it seems manager Roberto Mancini has landed his perfect transfer target. But Kun Aguero also represents the perfect signing for owner Sheikh Mansour.
His transfer fee was £38 million, and his wages over the next five years will cost £52 million, meaning the Argentine will cost City over £90 million in total (not including bonuses), but nonetheless for the owner and board of directors this bit of business could be financial gold.
After all, Aguero is the first player in the very highest echelon of world football to join Manchester City, which now puts the club into a new level of attraction, together with their participation in the UEFA Champions League, to both fans and sponsors.
He's also possibly the first City player in the new era, David Silva aside perhaps, who adds that "wow" factor on the pitch, with the sort of unnecessary yet incredible skills that fans would solely pay to watch, something which increases the value of City's main product—i.e. what they do on the pitch in matches.
Out of any Manchester City player, it's clear their costliest arrival could be the one to earn them the most money, especially if he can also deliver on the pitch and help City to all the prize, sponsorship and TV money which comes with doing well in big tournaments.
Not only that, but assuming he performs as well as expected, Aguero will also have a phenomenal resale value, and if sold could possibly earn City something like the figures that swapped accounts when Cristiano Ronaldo moved from Manchester United to Real Madrid in 2009.
With the secret to getting rich lying in a person's talent to generate huge revenue for themselves or their employers, it's no wonder the diminutive Argentine is being paid so handsomely.
A footballer with the potential to become one of Premier League's greatest ever players, and with the potential to generate as much for his club as Thierry Henry did for Arsenal or David Beckham for United, Sergio Aguero represents the perfect signing for everyone at Manchester City.
