A blistering three-goal burst in four minutes saw Manchester United sweep aside Swansea City to continue their impressive winning start to the Premier League season.
Both teams hit the bar in a frantic start to the match - Jordan Ayew's scooped cross for the hosts and Phil Jones' header for United - and it was the visitors who made their dominance pay on the cusp of half-time as Eric Bailly tapped in.
Having initially struggled to unlock their opponents' well-drilled defence, United then opened the floodgates after 80 minutes as Romelu Lukaku confidently struck his third goal in two games for the club.
Paul Pogba added a third two minutes later with a delicately lifted finish and, shortly afterwards, substitute Anthony Martial fired in low to give United a second 4-0 win from their first two matches of the campaign.
After thrashing West Ham on the opening weekend, it had appeared this would be a sterner examination for United against an organised and defensively diligent Swansea side.
Jose Mourinho's men seemed frustrated at times - Pogba had to be warned by referee Jon Moss after a quick succession of fouls - but after taking the lead, they seldom looked like squandering it against their spirited but limited opponents.
