Swansea City scored a deflected winner to record yet another 2-1 victory over Manchester United in the Barclays Premier League on Saturday.
The Welsh club beat United by the same scoreline in last season's FA Cup third-round tie at Old Trafford, before pulling off a repeat away performance on the opening day of the current league campaign.
Jonjo Shelvey's thunderous 73rd-minute strike, which deflected off the head of Bafetimbi Gomis, who was ultimately credited with the goal, means three of the last four meetings between these sides have finished 2-1 in Swansea's favour.
After Swansea had looked the more dangerous in the opening stages, it was the visitors who went in front thanks to Ander Herrera's deflected shot shortly before the half-hour mark.
Yet Swansea were level two minutes later, when Ki Sung-yueng got his boot to a Shelvey cross from the left.
United put Swansea under sustained pressure for long spells of the second half, but the hosts struck late on to subject Louis van Gaal's men to a first defeat in five league matches.
Robin van Persie's return from injury saw Radamel Falcao drop to the bench following a disappointing display at Preston North End in the FA Cup on Monday, while Swansea adopted an unfamiliar narrow formation as Gylfi Sigurdsson made his comeback from a three-match ban.
Garry Monk's new set-up almost paid off in the opening stages as Wayne Routledge found a gap in the United defence, but Sigurdsson's eventual effort deflected wide.
Gomis' powerful header from the resulting corner looked destined for the bottom corner before being cleared off the line by Herrera. The French striker also headed over soon after.
United offered little in attack early on and Van Persie was unable to find the target from a tight angle when goalkeeper Lukasz Fabianski flapped at a Wayne Rooney cross.
Swansea continued to pose the greater threat, with Routledge - given time to turn in the United box - sending a soft effort into the arms of David de Gea after 17 minutes.
Having saved his side at one end, it was Herrera who put United in front against the run of play at the other in the 28th minute.
Angel Di Maria found Herrera in space just inside the box and the Spanish midfielder guided a low strike into the bottom-left corner via the slightest of deflections from Swansea captain Ashley Williams.
That lead lasted just two minutes, though, as Ki - scorer of Swansea's opener in the victory at Old Trafford in August - turned in a Shelvey cross.
The South Korea international came close to applying the finish to another Shelvey centre early in the second half, but De Gea did well to rush off his line and thwart the attack.
Van Persie fired into the side-netting as United probed with a series of attacks, but the Swansea backline was holding firm.
And Swansea's patience paid off when Shelvey rifled home a winner from 20 yards, although the ball did take a significant nick off the head of Gomis.
United pressed forward, as they had done in search of a winner prior to Swansea's second strike, but the home side clung on for just their second win in eight league matches.
Swansea manager Garry Monk: "I don't know if today is better than the win at Old Trafford - it's quite even. It was a great result - what a fantastic day. The team have done tremendously well against a side like Manchester United. To take six points off Manchester United for the first time in the club's history is a great achievement. To make history for this club is fantastic for this team to be remembered and it is no mean feat."
"Whenever you go a goal down it is against the plan but I thought we showed a good reaction. That's what we did, we got a goal back straight away and finished the half OK.
"We came out in the second half and had to withstand some pressure - understandable because Manchester United are a very good side. I thought we defended very well and I can only remember them having one shot on target in the second half."
Manchester United manager Louis van Gaal: "Of course you can say we dominated the game but the only thing we could have done more was score more out of the chances we created. Today we were the unlucky team. I think we created enough chances. We were the dominant side in both halves.
"Conceding so quickly after opening the scoring was important. It was a throw in for Swansea and we should have been more organised. But it was a good goal by Swansea. Today we played well - only we forgot to score. We have to be more effective."
