Swansea City 2-1 Wigan Athletic: Andre Ayew scores winner for Swans
Swansea returned to the Championship play-off places, coming from behind to beat relegation-threatened Wigan.
Wigan took an early lead when Nathan Byrne smartly finished a counter-attack.
Swansea levelled two minutes later as Conor Gallagher set up fellow loanee Rhian Brewster to score his first goal since joining from Liverpool.
The Swans pushed for a winner in the second half and Andre Ayew provided it with a cheeky backheel.
The result lifts Swansea up to fifth place in the Championship, while Wigan remain second from bottom of the table, still two points away from safety.
Paul Cook's side may feel this was a missed opportunity to gain at least a point in their fight for survival, but Swansea were good value for their victory.
They had come into this match with high hopes after a productive January transfer window so far, with head coach Steve Cooper making full use of his contacts from his previous role in charge of England Under-17s.
Three members of Cooper's 2017 Under-17 World Cup-winning squad - Brewster, Gallagher and Chelsea defender Marc Guehi - have joined this month, and the two who started against Wigan, Brewster and Gallagher, made a big impression.
Gallagher, who had excelled on loan at Charlton earlier this season, slotted seamlessly into the Swans midfield, helping the hosts make a vibrant start to the game.
But it was Wigan, with only one win in their previous 15 matches, who took the lead after 16 minutes.
The visitors sprang a counter-attack on the left wing and Kieran Dowell played a low cross to right-back Byrne, who was allowed to wander into the middle of Swansea's penalty area, take a touch and pick his spot with a calm finish.
Wigan's joy was short-lived. Less than three minutes later, Gallagher threaded a fine through ball to Brewster, who swept a low left-footed finish into the far corner to score his first goal in senior football.
There was a buzz to the game at this point, played at quick pace with chances at both ends, Wigan's Joe Garner and Swansea's Ayew both heading wide from promising positions.
Although the tempo slowed a little, there was still plenty of goalmouth action in the second half, albeit more contained to the visitors' penalty area.
Bersant Celina, Kyle Naughton and Gallagher all went close with shots on goal as Swansea began to take control of the game.
And it was Celina who was the architect of the decisive goal, darting down the left wing past Byrne and pulling the ball back to Ayew, who deftly backheeled it into the net to score his 12th goal of the season.
Swansea were relatively comfortable from that point and, apart from Byrne's half-volley in added time which whistled narrowly over, Wigan seldom looked like salvaging a draw.
Swansea City head coach Steve Cooper: "I am pleased with the performance. We started well, we got on the front foot and looked to be the team we want to be.
"Conceding was disappointing, it's never good to concede, but to be fair the boys did not let it affect them and scored pretty soon to get back in the game.
"Half-time was important. We got some messages to the players. We felt we were not quite at the level we want be at. We weren't poor but we wanted to be better, and second half we were good.
"We looked a threat, we moved the ball, we were on the front foot. We pressed them better than in the first half and, in the end, scored a really good goal."
Wigan Athletic manager Paul Cook: "Same old, same old. We've been there before.
"Swansea started the game very strongly, they've got a lot of good players and have recruited well with Brewster and Gallagher coming in. Plenty of energy.
"We managed to take the lead and then we gave a goal away which you couldn't make up. But it's the way our season's gone. We gave away another cheap goal.
"I must commend lads for our honesty, they don't lie down. But we lacked quality that's for sure."
