I think people should remember he's still only 22 - only about 6 months older than Keinan Davis.
He won young player of the year in Belgium last year and has moved for a big fee, but he's still raw and it looks to me like his head still isn't quite right.
Personally I'd play him against Norwich as they are a poor defence. Tell him to be aggressive, stay on his feet and make his mark on the game, as he's got Davis and Kodjia chomping at the bit for his shirt.
Could be the making of him - and if it isn't it's time to start one of the others.
