#6 David Villa
David Villa may not have spent a significant number of seasons wearing a Barcelona shirt, but he was a crucial part of one of the best club teams in the recent past during his short stay at the club.
The Spanish striker was not able to play in his preferred central role at the club due to the presence of the indomitable Lionel Messi. Pep Guardiola used Villa on the left flank, and the change in position did not seem to hamper the striker's predatory instincts.
David Villa joined the Catalan club in 2010 from Valencia for a transfer fee of €40 million. He was no stranger to most of his teammates or the style of play and used his experience as Spain's premier striker to further strengthen his relationships with Xavi and Iniesta.
With Messi dropping into midfield to facilitate Barcelona's tiki-taka, Villa was afforded the space to do what he was good at: make runs in behind the defense and latch on to his teammates' exquisite passes.
The Spaniard was an integral part of Barcelona's three-pronged attack and linked up well with Messi and Pedro to effectively terrorize teams in Spain. David Villa scored a few stunning goals for the club, most notably including a curling effort against Manchester United in the Champions League final. His two goals in the 5-0 demolition of Real Madrid in 2010 will live long in the club's memory.
An injury to his tibia during the FIFA Club World Cup meant that David Villa spent most of the remainder of his time at the club on the sidelines. He left to Atletico Madrid the following season and went on to establish himself as a modern-day La Liga legend.
David Villa scored a total of 48 goals in 119 appearances for Barcelona, with several of his strikes playing a crucial role in victories against Real Madrid, AC Milan, Arsenal and Manchester United. With a return of two La Ligas and a Champions League in 3 years at the club, David Villa's time in Catalunya seemed to benefit all parties involved.
