United were 2-0 up early on thanks to Morgan Gibbs-White and a stunner from George Baldock, who later limped off with injury.
Goals from Billy Sharp and Gibbs-White’s second of the game saw United run out convincing winners, and leapfrog Middlesbrough into sixth spot ahead of their midweek clash with fellow promotion chasers Blackburn Rovers.
Here’s how our man rated United’s players, on an afternoon to remember at the Lane.
5. Jack Robinson 7
Solid as ever and looks to have grown under Heckingbottom's charge in recent weeks, deservedly keeping Ben Davies out of the side Photo: Andrew Yates
6. Rhys Norrington-Davies 7
Will be boosted by an assist for Baldock's opening goal, especially after questions about his attacking output led to him being left out of the team. Photo: Andrew Yates
7. Ollie Norwood 7.5
Sublime pass for Gibbs-White's opening goal, spotting the loanee's run and finding it with a beautiful ball for him to run on to and finish. Picked up a deserved booking for wiping out Piroe in the first half as the Swans looked to break clear, but missed the easiest chance of his career near the end. Could have scored a much harder chance soon after but it flashed just wide Photo: Simon Bellis
8. John Fleck 7
Signalled his intention from almost the first whistle with a driving run forward as United started brightly, and was much more involved as he has been in recent weeks. Not shy of putting a foot in either, which was appreciated by the Lane crowd Photo: Will Matthews
