In every game that I end up managing Man Utd, Wolves are always my bogey team.
back in CM03/04 they were languishing in League Two in about 2030, drew them in the FA cup at OT. Because they were my bogey team I played the strongest team available. I was still beaten 2-1
I havent played them yet in FM08 and so far only Derby seem to be my bogey team - I always draw against them

nearly cost me the title if it werent for Chelsea beating Arsenal in the last game of the season (i was one point behind arsenal)
Sheffield United are currently looking scary as in the start of my 3rd season 7 games in they were undefeated :o I am yet to play them however
