The tie between last season's FA Cup final opponents will be played at Stamford Bridge sometime between Friday 15 and Monday 18 February. The exact date and kick-off time will be confirmed in due course once broadcasters have decided which games will be selected for live television coverage in the UK.
The match will be sandwiched in between the Reds’ testing home games against Paris St-Germain in the Champions League last-16 first leg and Liverpool in the Premier League.
United reached the fifth round of the FA Cup for the fifth successive season after beating Arsenal 3-1 at the Emirates Stadium on Friday night thanks to goals from former Gunners forward Alexis Sanchez, Jesse Lingard and substitute Anthony Martial.
