He is already better than Henderson, imo of course. If there are any doubts, given the trajectory of his progress since he's joined us, he will be a better player than Hendo will ever be in 2-3 years.
If he goes on to join Citeh though, he's dead to me.
I don't buy that. Henderson was performing much better than he currently is a couple of years ago, if he hadn't been hit with a terrible injury, he would be a much better player now. He was providing assists and chipping in with goals. Henderson has 24 goals in 6 years so an average of 4 a season, Can has 11 in 3 seasons, so more or less the same. He was also alot more consistent at his peak, we arguably lost the title because of his ban after the City game, we've never even remotely relied on Can that heavily.
He's performed at his best early this season when the door was still open for him to potentially move, what's he done since? His usual one great performance in ten?
