As a side note to enjoying this title race was wondering how many Arsenal players may be qualified as WC.
Lets say WC means you are a top 10 on your position worldwide, it would be Saka and Odegaard atm, maybe Saliba Zinchenko and Jesus, but at least last two very ambiguous (co called system players, Zinchenko with a massive question mark defensively, Jesus in aspect of finishing, which is important enough at his position). Saliba needs to stop catching injuries.
Partey and Martinelli have games when they look like WC, lacks consistency though. As been sometimes White, but I would assume more offensive skills required to be qualified as WC RB.
I think they ride better as an unit than sum of their parts (should have done better with Cups though, especially being out to Sporting in EL is not a best look for a Premier League contender). By the way I am sure its similar case with us. Club, Pep, coaching staff, makes players better than in a different environment. Ask Sane, Sterling, Torres, Garcia all have landed among big clubs and my impression is they hardly improve or got worse.
