It might be time to cancel your plans for Monday, October 17 because it's Liverpool v Man Utd in one of the biggest games of the Premier League season so far.
The Monday Night Football clash between the two English football heavyweights pits Jurgen Klopp against Jose Mourinho.
Liverpool have looked electric at times this season, beating Chelsea, Arsenal and Leicester City, but they have been vulnerable too, most notably during a 2-0 defeat to Burnley.
As for Mourinho's United, a run of three straight losses in September spoiled a promising start, and their recent 1-1 draw at home to Stoke City suggests they are not quite back to top form yet.
The two sides have enjoyed some classic encounters in recent years, including Steven Gerrard's 38-second red card last year, and Liverpool's remarkable 3-0 win at Old Trafford in 2014.
