I feel like Iniesta's performance vs Manchester City at home right after his terrible personal tragedy provided some of the inspiration to fuel the team and really get them pumping. When someone does something so heroic and amazing as Iniesta did, everyone can't help but feel inspired by and feed off of that energy.
Ever since I saw him in the Spain game a couple weeks ago I could tell he was starting to feel it again. Now he's just turned up the level to 11, and we are SO much better for it!
