Rasmus Hojlund broke his 10-game scoring drought to seal victory for Manchester United in a thrilling Old Trafford encounter with Newcastle.
Kobbie Mainoo put the home side in front after 31 minutes when he applied a cool finish from 10 yards after being played onside by Kieran Trippier.
Anthony Gordon levelled four minutes after the restart.
Amad Diallo drove home his first Premier League goal just before the hour mark as Newcastle failed to clear a corner to put Manchester United back in front.
It was left to Hojlund to settle home nerves, stepping to his right before sending a low finish into the bottom corner for his 15th goal of the season.
However those nerves still jangled a bit, as Newcastle left-back Lewis Hall fired home from the edge of the box in the second minute of stoppage time but the home side held on.
Newcastle need a final-day win at Brentford to be certain of a top-seven finish.
Newcastle have now won once in 29 visits to this stadium and European qualification now relies on the failings of others.
The overall outcome means Manchester United have something to play for on the final day, which did not always look like being the case.
And, as Ten Hag pointed out at the start of his side’s lap of appreciation, his side finish their season at Wembley in the FA Cup final against Manchester City, when he promised his side “will give everything”l to win the trophy.
