Jamie Carragher was told to 'behave' by commentator Martin Tyler after aiming a joke at Manchester United during Fulham's 1-1 draw with Wolves on Friday night.
Michael Oliver oversaw proceedings at Craven Cottage, with Sky Sports commentator Tyler acknowledging that the Northumberland-born referee is a Newcastle United supporter.
Tyler noted how Oliver cannot referee Newcastle matches due to his support for the club, which prompted Carragher to joke about referees' potential affection for Manchester United.
