I say it comes down to Martin Jol vs. Stuart Pearce, with Jol getting a submission from Pearce. No rules streetfighting. Anyone?
Roy Keane for the win as soon as Sunderland come up for the Championship. Honestly, not sure there there is a manager in professional football who could handle Keane in a fight.
Otherwise it’s Pearce or maybe Mark Hughes.
Whatever happened to Bruce Rioch? He was a bruiser, and would kick the shit out of any of the current managerial crop.
