The answer is yes there are managers that could do better. But the real question is why would any of those managers want to come to Villa given the ridiculous financial restrictions in place. There are real problems with our squad both in terms of first 11 and depth but its pretty much impossible to fix this without having the funds to even loan in good players.
I can't help but think back a couple of seasons ago when Martinez rejected us. At the time I couldn't understand why someone who manages Wigan wouldn't jump at the chance to come to our club. But even a talented up and coming manger looked at us and the restrictions in place and said i'd rather risk relegation with my current club.
As much as its easy to blame the players and the manager the biggest problem is an owner who wants to have the team on a budget that will see us in constant relegation battles.
