Not a bad peformance.
Hart was outstanding, kept us within reality of getting a draw for the entire game.
Aguero's pen was poor but it's not often he fluffs it on the big stage. Freak accident.
Bigger Issues:
Yaya as CDM. Neville alluded to it, he just can't play in that position. He doesn't track back and leaves so much space in front of the back four. If you have to play him, play him as CAM.
Crossing/corners. A title challenging side can't kick a ball into the box well. Txiki needs to buy somone for RM, but given his purchase history, it'll be someone really average.
To quote Mark Radcliffe: "when we're good, at least we're much better than we used to be and when we are bad we're just as bad as we always used to be, so that's got to be good hasn't it?"
