The draw took place after the Reds eliminated Rochdale on penalties on Wednesday night in the third round of the competition, following a 1-1 draw against the League One side.
Mason Greenwood bagged United’s only goal of the night, while 16-year-old Luke Matheson scored for the visitors.
The Reds netted all five penalties after the conclusion of the game, to win 5-3 in the shoot-out and set up the fourth-round tie with Chelsea, the first time we have met them in the League Cup since the sides played out a nine-goal thriller in 2012.
During that remarkable game seven years ago, which went to extra time, Chelsea emerged as 5-4 winners, with Ryan Giggs (2), Javier Hernandez and Nani getting the goals for United.
