As John Giles among others has pointed out before, Sam Allardyce doesn't need any encouragement to attack the performance of referees. After last night's 2-2 draw against Manchester United, Allardyce was angry that the linesman had missed Robin Van Persie being offfside for United's equaliser.
After exaggerating by claiming Van Persie was two yards offside, the funniest part of the interview is after around 0:50 when with a bemused look on his face he says 'I don't know what's going on' because the linesman flagged Andy Carroll for offside in the first half.
It should also be pointed out that Linesmen can get dropped as well, Sam.
