TBF I was never really excited with us signing him. His highlights weren't even that impressive, which was worrying as it was the Dutch league. He just isn't a very talented player imo. He isn't good enough to displace any of our other options, Martial is better than him at literally everything, Lingard is better defensively, Mkhitryan is vastly superior to him etc.
I think a move to a smaller club, where he belongs would be best for both of us. Would love to be proven wrong but what does he actually excel at? It's as if he has nothing else in his locker but to cut in off the wing and try make space for a shot, something defenders figured out a few games into the season. It's no surprise his best performances were against terrible teams.
