FC Barcelona have won three continental doubles (League plus Champions League) in the past six seasons, two in the past three, and Pep Guardiola's current crop is widely considered one of the best, if not the best, squads in the history of the game.
But that doesn't mean there isn't room for improvement.
It's hard to see any player in the world displacing any member of Barcelona's vintage XI (Valdés, Abidal, Puyol, Piqué, Alves, Busquets, Xavi, Iniesta, Pedro, Villa and Messi), but a squad isn't only 11 players, and there are some positions where Barcelona could use some more depth.
Needless to say, not anyone can be a part of this FC Barcelona squad. Only world class talents have a chance to make it at Camp Nou.
The following list contains five players on the market (unrealistic targets were excluded) who could potentially make the squad even stronger.
