One question that's been bugging my mind for a while, has Can really improve in any shape or form since he first arrived to the club? Because he seems about the same to me.
He still is a wildly inconsistent passer of the ball, and a very careless one. His game intelligence and tactical understanding, if not about the same as when he first arrived are probably worse (certainly this season). But the biggest problem for me is that physically he still looks like a 35 years old veteran when he's not at his sharpest, which he rarely is until January/February, but his game still relays so much on him being that physical beast that makes him a giant liability on our side when his body is not there yet.
There still are the raw pieces of a very good midfielder, and he has a winner's mentality even if you wouldn't say so based on this season, but his lack of progress on his 3.5 years at the club are definitely a bit concerning, well considering that he stays that is.
