If true, and it appears likely that it is, it's disgraceful behaviour from Dyche. How on earth can a manager that has been paid millions from the club, much more than he's ever earned in his life and more than he ever will in the future, tell the club he's essentially finished and cannot perform his duties yet will not officially resign from his position.
I had a lot of respect for the way he handled himself as Everton manager, but that's all gone now knowing how much of a greedy arsehole he really is.
It's not too common any more for managers to resign, but plenty still do. You never hear of managers having told the club they cannot perform their duties, but you'd expect those that do to do the right thing and walk away without holding their hands out for every penny they are 'owed'.
Highly disappointing. Should he choose to be, he'll probably have options to stay in the Premier League this season as soon as Leicester fire Ruud or Palace fire Glasner.
