Marchisio's one big flaw is his physical weakness, in direct duels he often loses out with either speed or strength. Technically and tactically he is absolutely fine, but we really get exposed by directness when he is on with Pirlo, especially if Vidal is not on the pitch.
Looking at him and Giovinco we must use the antidote to Messi's hormone pills as a supplement for our youth players.
Having said that going the other way up the field he was one of our better players tonight, and his energy was excellent, as was Pirlo's.
