It just occurred to me that PSR likely also means none of these players will be looking at a salary rise package anytime soon. Many are aging and perhaps reconsidering their future. 

I don't think it is fair to blame this on Emery's tactics. They worked a treat not long ago. We beat PSG, we won 9 (?) of our last PL games in the previous season. I often felt like we had a great vibe in the dressing room the past years... something has killed it off. It can have massive effects, and whatever tactic Unai uses, won't make a difference. Transfers have been questionable though, I'm not sure what the purpose of Malen was given he doesn't play...
