Still had the stuff that made him potentially great. The dribbling, the creative passing, the intelligence.
His type of creative passing is something that he does and only a few top players do. He passes not between the line where the striker is running. If the striker is running between CB and CB, most players try slotting it through there, which defenders expect. But he goes between LB and CB to catch them out. He used to do it a lot in our u23s and even first team.
At the beginning of the game he wasn't holding the ball up when played to feet, instead being knocked off the ball, but after a while he was holding off Telles and Maguire (!) and starting attacks. I honestly don't think he'd look out of place if he was still here, but he's definitely not reached his potential. I don't care what anyone says, he was a top talent.
I have my own views on why he failed (handed the no.11 then shipped out on loan etc). LVG wasn't a good fit for him at all.
