Michael Carrick has called for both teams to show respect when Manchester United take on Liverpool in the Premier League this weekend.
The veteran midfielder said that he is anticipating a "special" atmosphere at Anfield on Sunday, with both sides bringing their top form.
He said: "Everyone's got a huge responsibility to respect the situation. Hopefully the football will be celebrated as it's one of the classic football games worldwide.
"These games are a one-off, form goes out of the window, the atmosphere is that little bit more special. We're expecting Liverpool to bring their best game and we'll have to bring ours.
"To play in a game like that, they're the ones you remember. As a player you appreciate what it means to the fans."
Carrick scored the only goal in United's 1-0 Champions League victory over Galatasaray on Wednesday evening.
