Manchester City have apologised to Liverpool after a section of their supporters interrupted a period of silence to mark the Hillsborough tragedy before Saturday's FA Cup semifinal at Wembley.
A pocket of City fans could be heard chanting after referee Michael Oliver blew his whistle to signal a moment's reflection in memory of the 97 Liverpool supporters who died at a 1989 FA Cup semifinal between against Nottingham Forest.
The noise triggered an angry reaction from the Liverpool end as boos rang out in response and a City spokesperson said: "Manchester City are extremely disappointed with the actions of some City supporters during the minute's silence before today's game.
