Mitchell is Howe’s boss and Eales is Mitchell’s boss. The problem is that Howe’s influence at the club was relatively high when Mandy was there. It’s highly likely that this is why Ashworth left - he may have felt he was being undermined.
Just because Eddie’s done an amazing job with the team, it doesn’t mean that nothing should change at the club as we aim to move forwards. Mitchell’s ‘not fit for purpose’ comment was clearly aimed at the mess of losing Minteh snd Anderson - caused by the fact that we never sold anyone thus leading to a dead end with PSR. I think Eddie did an amazing job with the players signed but he failed to understand PSR enough that we should have moved some players on (the overriding loyalty to players that he has).

IMO PIF recognized this and have made adjustments - Mandy out and Mitchell in. It’s for the good of the club and everyone needs to accept and work together in the new structure.
