You’ve just reiterated my point. You say ‘Warne who had players willing to play for him AFTER the relegation’ This is exactly what Richardson is dealing with now. He has players who won’t or who haven’t showed willingness to play for him.
Let him go through what Warne did and choose his players who he can share the ethos of how he sees the club moving forward then judge him after say 10-12 games. Just sacking Managers all the time doesn’t help the situation.
