The way the moments occured in the Inter game, with those plenty of arial passes onto PK area, he definitely was a missing puzzle piece. Even if he does not score, he is still like a wedge not allowing to completely shut the opponents door.
I don't know if he can be lined up on Tuesday. Probably not, even if he was healed, he's off the routine so the expectations should be tamed. I really would want Barcelona to advance but despite Inter recent problems to get results in Serie A, somehow they can find good luck in this competition.
