Eddie Howe named three goalkeepers on the bench, such was the paucity of senior outfield options, as well as three teenagers, and handed a first home Premier League start to 17-year-old Lewis Miley.
It was Miley who set up the opening goal, punching a wonderful pass into the feet of Alexander Isak - back after missing the previous five matches - who finished emphatically in the 13th minute.
Raheem Sterling levelled ten minutes later, but in the second half, captain Jamaal Lascelles headed United in front once more before Joelinton made it three just seconds later.
Anthony Gordon rounded off the scoring in the 83rd minute and Howe was able to give debuts to Academy products Alex Murphy, Michael Ndiweni and Amadou Diallo to make it a proud day at all levels of the club.
