what i liked with him, is he played at least 2, maybe more of those defence cutting through balls that Tielemans does so well.
Granted they didnt entirely work, but the fact he can see the pass and try to make it is a really good sign for me, once he settles, learns Emery's ways and gains some confidence, i think he is going to be very good.
he also looks comfortable on the ball and driving forward with it, the lad looks like he has oodles of potential to me.
