They were actually on the same side in Gary oldman's 1980's Football Hooligan Film The Firm so no fight there.. I would go with Phil Mitchell, I dont think Jim is too Clever if you go at him as Phil would, Phil is no Vernon ! "Arrr What About you now Phillip..."
But Dennis Rickman had the better of him, as did Grant Mitchell and dirty Den - I reckon Jim could take him.
Phil, in his prime. The bloated Phil of late is still a savvy fighter but hasn't the agility and speed of his youth. He was about as hard as Grant back in the day.
I forgot to mention that Pat Butcher is the special guest referee. The fight is also at York Hall, Phil Mitchell's back yard. how with these minor details affect the fight?
