we should not be letting the kid decide where to go. if the club had several offers, then the club should decide which it thinks is best for his development. This strikes of a stroppy little kid throwing his toys, which is how Lookman has appeared for most of his time here (storming out of the car park before a game when he wasn't in the squad etc).
I think his attitude isn't great, and he thinks he is further up the pecking order than his current ability suggests. He has pace, but at the moment that's about it. He is weak on the ball, gets dispossessed easily and makes some bad choices for passes. He also doesn't work hard for the team to win the ball back.
A loan may help his game management and decisions, if he gets some game time, but it won't help him become a bigger stronger player. I just think he is too lightweight to ever make it in the top half of the prem.
