Partey has been really good for Arsenal, so not sure what you mean by this. Not being as good as him does not mean Éderson isn't good enough for Premier League. His profile is actually perfect for Premier League, because he has the athleticism, strength, tenacity and energy, probably more so than Partey who is more of a holding defensive midfielder. Ideally, he would be a better passer, but he is more than good enough and has shown it in Champions League previously. Very few midfielders in the league are metronome midfielders with exceptional passing ability, yet they are able to play at a very high level because they have a lot of other qualities, and I reckon Éderson could do the same. He could be our own Bruno Guimaraes if he keeps on developing.
