2 things here:
1.) He gave up more than "one or two" passes this weekend, and some of them in really bad areas of the pitch. Had Milan been better, we could have been in trouble.
2.) His shooting was horrible, probably just an off day cuz a lot of the times we will see him at least get them on goal (ex. Parma)
~Bad game from him, but not an extension of his abilities. He will pull a better performance I'm sure next game, who knows Pirlo/Marchisio might be as bad in the next game and Vidal will be the one to pull us out. He puts in the effort to overcome it, so I am not worried.
Biggest concern is the pasing and losing possession, he needs to concentrate more on this.
