He is now approaching the pinnacle of his career and can't deny he's having a good season so far.
But the thing is, first, Veronique won't accept a wage cut and will only ask for more. Second, he's 27, so most probably he won't make any progress. Third, despite his goal & assist numbers (in this season), most of the time he is still invisible (if not useless) in the build up phase and adds little on the offensive end. His biggest advantage is physical strength and consistency. He has good ground duel ability and seldom loses the ball. But that's all. And forth, like everyone is saying, contract year effort.
I say not extend.
