Cesc has actually been one of Barca's best players in the 1st half, and Iniesta's actually playing in the middle. I honnestly don't see what Villa will add right now
I wouldn't sub in Villa yet. But at 60-70 maybe if it's 0-0. We could use that away goal, and Villa does all kinds of contributions towards us getting that. That said: we're cool like this.
Pique and Carvalho should make a gentleman deal to both hit each other and get reds. More entertainment as more space, and neither team having to worry about CB with a yellow.
