I had a hard time choosing between Iniesta or Alba cause I think Jordi has been absolutely superb in his first season at Barca but I couldn't go past the Don. So honourable mentions to Jordi Alba at the least.
Busquets before his back injury and Iniesta, easily. Iniesta was contending (in my opinion) with Messi for best player in the world for a while in the first half of the season, he was so dominant and consistent. Busquets again performing on an incredible level, like last season; irreplaceable.
Iniesta was more impressive in Champions League compared to Messi. I know he saved us vs P$G and Milan, but overall in all games Iniesta was the better player.
Hard to choose between Busquets and Iniesta. We really missed Busquets' presence in the second half of the season, another one of the players who played on through injury in some games.
