Also recall Robbie Fowler telling a referee (Mr Elleray?) a penalty he'd awarded against Arsenal was wrong, but the official didn't change his mind.
It was the late Gerald Ashby who gave the penalty and, as you say, refused to change his mind in spite of Robbie Fowler's protests. Fowler took, and missed, the subsequent spot kick, although Jason McAteer (IIRC) netted the rebound.
