The win means United provisionally leapfrog Arsenal into fifth place, and move within four points of Manchester City with a game in hand.
Henrikh Mkhitaryan doubled United's lead 46 seconds after the interval and the game petered out, with Sunderland offering little in response as they failed to score for the seventh league game in succession.
Despite that, more than enough folk on Twitter seemed to think the United boss was asking about the song being sung by the away supporters at that particular moment.

Mourinho left David De Gea out of the squad for the Sunderland game but said he was confident he would be fit in time for next Sunday's meeting with Chelsea, with Sergio Romero set to continue in goal against Anderlecht.
Demarai Gray released Islam Slimani to level in the fourth minute and six minutes later, Marc Albrighton's free-kick from wide on the left embarrassed Joel Robles to put Leicester ahead.
Of Ibrahimovic's performance, Mourinho added: "You need these players sometimes to make it and normally every top team has a couple of them that can make a difference".
