The EFL has already confirmed that the Carabao Cup semi-finals will revert to being two legs, after one-off games last season, including the Manchester derby between United and City at Old Trafford.
Another thing to note is the FA Cup fourth round is taking place later than usual due to an additional international break between 24 January and 1 February.
Meanwhile, United’s first 2021/22 FA Youth Cup tie must be played before Saturday 11 December.
