Referee Michael Oliver cut short the commemoration to the victims from the 1989 crush before the FA Cup semifinal, which City lost 3-2 at Wembley Stadium.
I would never have thought that this is Manchester City. Some people didn’t understand the situation and that’s not nice. That’s really wrong in that moment but you can’t change that and it’s nothing to do with City and we accept the apology,” Liverpool manager Jürgen Klopp said.
The chanting came from the end with City fans at the national football stadium and it was followed by boos from Liverpool supporters.
Amid the noise, Oliver blew his whistle to signal a premature end to the intended period of silence that had seen both sets of players gather around the centre circle.
“Manchester City are extremely disappointed with the actions of some City supporters during the minute’s silence before today’s game,” City said in a statement.
“The club sincerely apologises to all those connected with Liverpool Football Club.”
A crush before the 1989 FA Cup semifinal between Liverpool and Nottingham at Hillsborough Stadium led to the deaths of 97 Liverpool fans.
