Atletico Madrid XI if they hadn't sold their best players

Striker: Sergio Aguero (Manchester City)

Sergio Aguero scored 20 times in the 2010-11 La Liga, the most behind only Ronaldo and Messi.

Sergio Aguero has been at Manchester City for so long that it's easy to forget that he, too, was once an Atletico player.

Signed from Argentinian side Independiente in 2006 for a then-club-record €20 million transfer, the striker was initially an understudy to Diego Forlan, but his precocious talent soon saw him join forces with the Uruguayan up front.

I swear whenever people compare Sergio Aguero to any other striker they ALWAYS forget about his time at Atletico Madrid. The boy was literally generational. 147 G+A in 230 games, a contribution every 117 minutes all at the ages of 18-23. pic.twitter.com/3ilnraGk2T

His blistering exploits throughout the next five years made him one of the best young attacking talents in La Liga and beyond.

Aguero netted 101 times from 234 games in all competitions, lifting two trophies along the way before Manchester City snapped him up in 2011. And the rest, as we all know, is history.

Striker: Radamel Falcao (Galatasaray)

Radamel Falcao reinforced his status as the world's best striker at Atletico Madrid.

Radamel Falcao arrived at Atletico Madrid on the coattails of Aguero's exit as the Rojiblancos looked to cement the attacking void left behind after the Argentine's exit.

Atletico Madrid signed up Falcao on a then-club-record €40 million transfer following the Colombian's blistering exploits with Porto, where he averaged 0.87 goals per game during a highly successful two-season stint.

A deadly finisher back in the day, Falcao replicated those heroics at Atletico Madrid too, scoring 70 times from 91 games. He played a key role in guiding the side back to Europa League glory in 2012 as the club also enjoyed UEFA Super Cup and Copa Del Rey success.

However, just like at Porto, Falcao played only two seasons at Atletico Madrid before jumping ship again. This time, Falcao moved to Ligue 1 side AS Monaco, where he struggled with injuries and a massive dip in form. Falcao now plies his trade in Turkey with Galatasaray.
