United secured a place in the hat after beating Championship side Watford 1-0 at the weekend and it has now been confirmed that we will face Liverpool at Old Trafford in the fourth round.
It's a huge game, which is set to take place on the weekend of 23 and 24 January, with an exact date and time yet to be confirmed.
As there are no replays in this season's cup, the tie will be settled on the day, with 30 minutes of extra time and a penalty shootout called upon if necessary.
Of course, we're no strangers to the side from down the M62, who we're set to face in the Premier League this coming Sunday.
