The Premier League gave supporters as much notice as possible by announcing this potential fixture date ahead of the FA Cup fourth-round weekend.
Both teams advanced to the FA Cup fifth round by 3-1 scorelines, Leeds at Accrington Stanley and Manchester United at home to Reading FC.
The Premier League also acknowledges the unique circumstances of the teams playing each other twice in the same week, with Leeds United vs Manchester United scheduled for Sunday, February 12. This is to avoid potential fixture congestion later in the season.
