I'm not advocating for guys who can only cross the ball. But, a bit of variation wouldn't hurt, I would have no problem if these guys did that and could put a cross in when it's on, like the players at City and Liverpool. They just can't.
He's not really an out and out winger either, although he can play there. When I've seen him there, he prefers to come inside, he just looks more comfortable and better at operating in those central areas.
So, he's not really going to solve the RW problem and it would be pointless to add him and expect him to be another one the same as what's already there for the LW. He's not going to want to come and play as a backup to Bruno either. It will only make sense if he's going to come in and fill the hole that will hopefully be left by Pogba in the summer.
