Heh rename the manager or not, doesn't really matter, you'll still loose to the mighty Rangers
word of warning though, it seem Naismith is made a bit too good in this game, and Boyd not enough, but that's just my opinion. Ferguson is on fire, Thomson is rated higher than Fergie (probably due to age) after that there ain't anything of note with the default Rangers team, although at the start it seems that Carrol is better than McGregor but if ALan gets a few games he quickly becomes number 1.
As for the Celtic team it's the usual suspects, Boruc is again a legend in the game,
Oddly enough though Celtic tend to bring in a striker (Eddie Johnson in my game) and stick with the strike force of the new striker and Jan Ven throughout which means Killin, McDonald and (of course) Rioden tend to get really unsettled really quickly. Oddly enough it seems that Kennedy seems to be Celtic's number 1 defender, and then O'Dea.
Aberdeen have been GREATLY weakened for some reason and they always seem to prop up the bottom or near enough, along with Gretna of course. Dundee Utd and Motherwell tend to do really well. Hearts have their moments but again, nothing special and Hibs suck mainly cause they only really have one good player left in Steven Fletcher (who is too expensive to buy)
