The main issue with Ange is how it looks like we wanted to take the Harry Redknapp approach again and have somebody who would put an arm around players demoralised by Conte and the Portuguese axis and get them playing freely once again
This issue is that while Harry Redknapp did have an ego, it didn't really manifest in any negative ways until his inexplicable tinkering with a working system when he was batting his eyelashes for the England job, but with Ange the ego has been far more apparent and is a large reason for so many of his press conferences being needlessly tetchy since at least October
I'd also suggest ego for how he undermined the logical decision to drop the defence back 20 yards during the injuries by not having the midfield drop at least 10 yards back, which is why balls over the top have been routinely marooning our midfield while inviting pressure on our defence since January
Ange’s coaching issues or lack of them are his problem. Even now he’s just coaching the system rather than the players. Ruben Amorim seems similar and he also isn’t getting the results required.
