His first action was very sloppy but he was nervous on his debut so it's understandable. After that he made some dangerous runs and had some decent crosses. Not a notable debut but it was 10 minutes and an important experience for him.
I thought it was a promising debut. Far less selfish than he ever was at Everton so maybe the argument he won't be at Barca due to their quality has a bit of weight. Or maybe he learnt he can't win a game by himself, if so he migh get a lot of game time next season.
He still has to work on his left foot both dribbling left and shooting/crossing.
