Koeman and especially Silva are not half decent managers.This is just not true.
Davies Coleman and Siggurdson would not have many if any premier league takers, if they did they’d be lower bottom half teams. Same as Keane.
Any half decent manager would get us mid table? Koeman and Silva had us in relegation trouble and one of the best managers of all time had us tenth.
People need to stop over estimating this squad. Most of these are not good players and there’s a few very good ones dragging them up.
Davies and Sigurdsson are not first choice players for us if everyone is fit so you can only compare them to what the rest of the league have in reserve. Coleman is first choice but will almost certainly be replaced this summer
Keane was very good under Ancelloti and would have lots of clubs happy to play him. You are under estimating how poor the league really is.
The team itself needs an injection of quality and pace but the Moshiri will back the new manager. He will also pay the manager top wages. Let’s aim higher rather for settling for somebody
