I'm not going to go into it too deep here, but I believe Sissoko is being put in a position which he isn't suited to at all. Not a surprise we saw him at his best in a 4-4-2 or a 4-2-3-1 where he could stick to the defensive midfielder role.
A 5 years old blind kid could have done a better directing job than this. Do they pick up directers out of the streets in Italy. Many times the players with the ball is out of the picture, I wonder if they also taught those cameramen zoom in & zoom out in school.
Camoranesi on for Diego and Candreva on for Sissoko in order to provide some width, I think we'd really put Sampdoria under pressure then and stretch a far from infallible backline.
