Country: England
Statistically anyway, Saka had a better season under Emery, with most of his games at LB.You can dislike Arteta all you want, but Saka and Smith Rowe have both played well under him and almost certainly enjoy working under him at this point in their careers.
Do people who think ESR might leave, only think/hope he does because they hate Arteta?
I have no proof but looking at how other players have stagnated I’m pretty sure Saka could be even better than he is now playing in a team that creates more than 2 chances a game.
