When it comes to championship:
Villa, Newcastle, Norwich, Derby and Wolves iirc have 4m or more
Barnsley are a side with low expectations
And Sheffield Wednesday would be a good club if they were not spending so bloody much!
If you dont mind dropping to League One, remember Bolton, Charlton, Coventry and Sheff United are there, in terms of money though I believe Sheff united are the better side initially, but Coventry can make money in game.
