Also want to mention that it’s part of the manager’s remit to give the players the platform and confidence to maximize and display their individual qualities consistently. That was what Wenger was brilliant at in my opinion. Just letting players go out there and be the very best they could be. You would hardly find a player who failed under Arsene go to another club and then suddenly become a world beater like Salah has shown at Liverpool or Lukaku did. Even Mane was derided as a wastrel by many when he went to Liverpool from Southampton. Look at him now. One of the very best and most impactful players in the league over the past 3 seasons.
We have a few players that are just underperforming or have lost form badly under Arteta, or have been sacrificed in pursuit of his ideals. Imagine Wenger loaning out Saliba regardless of whatever disciplinary issues he may or may not have had, or not getting more from a talent like Pepe? Pepe today would look like Salah under the Frenchman, and Auba would definitely be getting many more chances in front of goal. Or a powerhouse like Partey? And this is not romanticizing the past. I was one of the most critical of Arsene when he started losing focus, but we know what he was capable of turning players into.
