Work in progress. It's expected to have some good games and some bad ones. I think he struggles with the volume of games, he is not the most gifted player in terms of stamina and speed. He can have games where he looks sharp and decisive, followed by a game where he looks as if he did 50 stadium laps prior to the match.
In this game and the Atletico game, he looked slow and ponderous. In other games, he looked one step faster and more tenacious. I want him introduced in a rotation system as soon as more players come back from injury. It's not right to play 17-19 year older every 3-4 days.
One thing with him is that he so far has a lot to learn about where he is in space. Sometimes, he had space behind him, but he was unaware of it and acted as if he was under pressure when he wasn't. He should learn to think quickly and inform himself at all times about where he is and where the opponents are, something which Gavi does better, but even he has to improve. It's one of the things you get better at with experience and forming better relations with your teammates.
