The number of goals and assists he has provides for Ajax speak for itself. The guy is making a switch from a different league to PL which many players find a struggle initially. 9 games are not enough to be judged on your good footballing abilities of 4 years.
He's played more than 9 games mate and he hasn't looked good in one of them. I believe there is a player in there, but a player potentially better than Barkley? No, sorry you can sell that bridge to someone else.
