Crazy take that.
It's not the quality of the players, it's what you do with them, and much of what Cooper is doing with them is simply wrong. (I don't currently have the time to go into tactical detail but the positional and personel changes he's made have set us back massively). We won the league with an inferior squad in comparrison to perhaps 10 other teams that season.
To suggest there isn't much Cooper can do to improve the situation is, without wanting to offend, is ridiculous.
If you can tell me what his system is, what his style is, what his tactical aims are then I'd love to know.
If we are going down the 'players aren't good enough route', think about how this group of Premier League players didn't have a shot on target against League 2 Walsall until the 78th minute and ask honestly, is that because our players are worse than Walsalls, or is it the way we set them up to play? It can only be the latter.
