@ zizinho, I disagree. Weirdly enough Marchisio is someone who used to be deadly as box to box CM when he was younger, but as he grown older his instinct for goal and runs has not been anywhere close to previous levels of his. It matters alot he is not playing with someone like Vucinic for past 2 seasons, takes away big time from opportunities he used to get, but still. Needless to say, he is ALOT better as DM, as someone said, pretty world class almost. As CM to the right or left in a trio, he is good, but not that integral to the team, his shots just outside the box or runs into it usually lead to very little, say compared to someone like Vidal who is super efficient in this role (or was). While in reverse, Vidal is VERY bad choice for the calculating and stationary role of a DM that Marchisio has shown he excells at, latter has the tactical patience and resilience to do this quiet role, while Vidal is all around action energy rocket that needs to be all over to effective.
