I watched the match last night specifically to see him.
First impressions were that this kid has it all! Everything went through him last night.
The only criticism I have is he was quite selfish on at least three occasions there were people he could have played in but chose to take it on his self.
This is something which could be worked on easily enough and what better players to learn from than Silva, Nasri, Yaya etc.
Also at his age I think he'd accept squad rotation and sitting games out whilst he developed. Great siging imo, just a shame were not linked with him.
