With the regular programme ending on Monday night, the Reds have secured a spot in the end-of-season knockouts.
Sixteen teams are left at this stage, with United ending up in 12th spot in the 26-team table, on the back of an entertaining 6-3 win at Southampton in the afternoon.
This term's new format means the title winners are decided in this fashion, rather than topping the league, a feat that was achieved by Tottenham Hotspur.
A top-12 place has also assured United of entry into the 2024/25 Premier League International Cup, at Under-23s level.
