The England international added to Gabriel Jesus' early strike to seal a comfortable win at Turf Moor as Pep Guardiola's men secured a 13th successive victory in all competitions.

However, they were pierced once again seven minutes before the break when Sterling stabbed home from Ilkay Gundogan's driven cross to take his tally for the season into double figures.

Ollie Watkins briefly gave the home side hope when he made it 2-1 with nine minutes remaining, but Lingard's second two minutes later effectively finished the game.
