actually we have a real luxury problem in midfield. there are no questions about sissoko, he's a starter for sure. but aside him you can choose out of zanetti, marchisio, tiago and poulsen. all of them could be starters in a lot of top-teams.
a lot of people don't rate poulsen highly, taking only juve matches into consideration i can understand it. but i followed him in his 4 seasons in germany and the european competitions. i really don't like schalke but i have to admit he was one hell of a defensive midfielder.
guys, zanetti is the shit! have you seen his latest performance? that was after an injury break of about 4 months. incredible stuff.
marchisio is a real prospect and should get as much minutes as possible to develop the best possible way.
tiago is different to every other midfielder in juve. he's not a real dm. i'd like to see him in some home game in a 3-man midfield with sissoko and marchisio behind giovinco-del piero-amauri.
as you see we have 4 potential starters next to sissoko and each of them has his specialities.
