BBC One's Match of the Day FA Cup broadcast has been repeatedly disrupted by a strange noise - which some viewers identified as a phone sex noise prank.
At one point Gary Lineker asked fellow pundit Danny Murphy to stop making the noise - but the former Liverpol midfielder denied it was down to him.
He later revealed a mobile phone had been found taped to the back of the set. "Well, we found this taped to the back of the set. As sabotage goes it was quite amusing", said Gary.
