Okay, but there's a massive difference between Raheem being the fall guy last season and Grealish being the fall guy this season. Raheem had very good goal and assist numbers and the criticism of him was over the top. Grealish doesn't, and for some reason he's the only person who's above Pep's "you only play if you deserve to play" policy.
People act like Raheem left because he didn't want to fight for his minutes, but if we're being fair to him, even when he or Foden deserved the minutes they were often given to Jack, who was doing next to nothing. Why stay and sit on the bench to watch someone nowhere near as good playing instead of you?
