Quite the opposite, really.
Randy Lerner doesn't know much about football.
But he also knows that he doesn't know much, and thus absolutely trusts MON's judgement.
Hasn't Lerner been a football fan (taking intrests in Arsenal, Villa and Fulham) since he was at Cambridge Uni in the early/mid-80's?
Abramovich probably subscribes to that theory but, since he sacked Moaninho they've only won CC and FA CUP...
