A wonder goal from Jonjo Shelvey fired Swansea on their way to a comfortable win over Aston Villa that all but secures their Premier League place for next season.
The midfielder lobbed Brad Guzan with a stunning 45-yard volley that sent the Liberty Stadium crowd into delirium.
Wilfried Bony had opened the scoring before Gabriel Agbonlahor levelled for the visitors. However, Swansea dominated the second half and were rewarded with Shelvey's strike before Pablo Hernandez made it 3-1 and Bony added to his tally with an injury-time penalty.
If Norwich fail to beat Manchester United this evening, Swansea are safe barring miracles from Cardiff or Sunderland.
Villa, meanwhile, are now without a win in six matches and only four points above the relegation zone with a tough run-in.
Despite his team's dismal form, Villa boss Paul Lambert named an unchanged side from the one that drew 0-0 with Southampton last week.
Swansea's interim manager Garry Monk also stood by his starting XI, and with good reason. The players who toppled Newcastle last weekend rewarded him with the club's first back-to-back league wins in 58 games.
Six minutes in, both sets of fans stood and applauded for former Swansea midfielder Ferrie Bodde, who was in an induced coma after suffering pneumonia. Little did they know he had come out of that state and was watching the game from his Dutch hospital bed.
The Swans may have been without last season's top scorer Michu – out once again with an injured ankle – but this term's most potent marksman Bony did not need long to put his side in front.
The Ivorian opened the scoring in the 10th minute when he latched on to a through-ball from Shelvey that pierced Villa's high defensive line.
Centre-back Nathan Baker appealed for offside, but the flag stayed down and Bony side-footed past Guzan with ease to bag his 14th league goal of the season.
Villa enjoyed decent possession in the first quarter but were restricted to long-range efforts from Agbonlahor and Marc Albrighton, neither of whom could test Michel Vorm.
In the 22nd minute the deserved equaliser came thanks to some slick football down the right. Karim El Ahmadi slipped the ball down the flank to the overlapping Albrighton, whose curling cross was met by Agbonlahor from close range giving Vorm no chance.
The goal ended a Premier League drought of three hours and 42 minutes for Lambert's charges.
A wondrous strike from Shelvey put the Swans back in front three minutes later. After chesting down Villa captain Ron Vlaar's clearance kick, he hit a missile of a volley from 45 yards that cleared the unsuspecting Guzan and curled into the top corner.
Bony tested Guzan with a low-shot from 20 yards, but the American had it covered.
Swansea left-back Ben Davies forced a save after the break when he fired in a left-footer and Shelvey also tested the busy Villa keeper with a low drive.
Jonathan De Guzman should have extended Swansea's lead when he shanked the ball wide from a Wayne Routledge cross on the hour.
Monk's side continued to probe and press and were rewarded for their dominance when Hernandez made it 3-1. The Spaniard was free at the back post when Shelvey crossed, cut in field and scored via the head of Ryan Bertrand, who was back defending the goal line.
Villa rarely threatened the home goal in the second half and their misery was compounded in stoppage time when Baker pushed substitute Marvin Emnes in the back and conceded a penalty.
The result from goal-hungry Bony - his 15th league strike - was never in doubt.
