A- Marchisio is as good as a passer as Vidal has shown so far.
B- Marchisio is better technically than Vidal
C- Marchisio so far has done his main job good enough in all the games, wich consist of protecting Pirlo and staying back covering for him, wich wasn't done by Vidal when he played alongside him in the second half yesterday when he tend to go forward leaving us very vulnerable to counters which was clear in the second half.
D- Vidal is a box to box MF so he needs to adapt to his new role and understand it before he can be trusted to play there. That's why Conte played Marchisio in all our games.
E- Melo you are just a hater
