I agree. He inevitably becomes a short-term, one-year appointment, no matter what happens.
Either we fail to get promoted, and he gets sacked. Or we get promoted under him, and then he's the wrong man for the task of staying in the Prem. In which case, we'd need to sack him before the new season starts anyway.
If we kept him for the PL, the style of play would see us in Southampton's position. On for the record low-points, top of statistics like 'Errors Leading to Chances', 'Errors Leading to Goals'.
The possession game can work when you have better players than your opponent. But now every team presses as a team, it just doesn't work when you have lower-quality players.
