Bruce said: "It's quite ironic. Matty Longstaff's beaten them in his first game and I've been going 20-odd years. I'm delighted for everyone concerned, and of course the response was the great thing.

"When it fell to him – he blasted one in here against St-Etienne [in pre-season] in exactly the same position, and we've seen him in training.

"'Surely not', was the call, but he smashed it in the net. It was great."

Bruce went back to basics after last weekend's 5-0 drubbing at Leicester, but boosted by the return from injury of lively winger Allan Saint-Maximin and the energy provided by the Longstaff brothers, saw his team turn in a vastly improved display just when they needed it most.

The win was thoroughly deserved as the visitors, who failed to muster a shot on target against AZ Alkmaar on Thursday evening, once again proved blunt in attack and were made to pay for it by the younger Longstaff.

Head coach Bruce said: "He trains every day with a big, beaming smile on his face, he's refreshing, wants to play, he's a great kid and I'm delighted.

"Typical of him, the first thing he said to me coming off was 'Thank you'. It's ridiculous after what he's just done."

If Bruce was thrilled to have taken the wind out of the sails of some of his critics, opposite number Ole Gunnar Solskjaer cut a frustrated figure as he assessed the wreckage of a defeat which left his team in 12th place in the table, 15 points adrift of leaders Liverpool.

The Norwegian said: "We have given ourselves a very, very tough task to get into the top six, never mind top four, and we've got to get results straight away.

"We need to get on a run, get momentum. I can't give you what's acceptable – every game should be one that we should look to win at this club."

Things might have been different had defender Harry Maguire buried a free header on the stroke of half-time – but his manager did not attach too much blame to the £80million summer signing.

The former United striker said: "Yes, but that's football. I missed bigger chances, seriously.

"If you're 2-0 up and your team is winning every game, he'll close his eyes and score on that one. At the moment, it's just not going for us and Harry knows he could have, should have scored.

"We know it's a big opportunity, a big moment in the game."
