This is a good question - I enjoyed played as Derby last season, or at least for one game, where I played against my mate as Man U - he led 2-0 at half time, but I realised I was trying to play my normal pass-based game, so I shoved on a defensive midfielder for one of my two strikers, just had Howard up front, and he scored three headers in the second half and I won 3-2.
This year - Aston Villa are a very well equipped team - also West Brom have a few very good players too.
