Bastian Schweinsteiger marked his first Manchester United start for a year with a goal and an assist in a convincing FA Cup win over Wigan.
Marouane Fellaini got on the end of Schweinsteiger’s cross to put the holders in front just before half-time in this fourth-round tie.
Chris Smalling made it 2-0 following a cross from Anthony Martial, who set up Henrikh Mkhitaryan to tap in the third.
Schweinsteiger completed the scoring with an overhead kick from close range.
Wigan, 22nd in the Championship, had given a good account of themselves before conceding three goals in 24 second-half goals.
United, who made nine changes to the side that faced Hull in the second leg of their EFL Cup semi-final on Thursday, sent on substitute keeper Joel Pereira, 20, and defender Axel Tuanzebe, 19, for their debuts.
