Swansea City climbed out of the Premier League relegation zone on Wednesday (NZT) with a deserved 3-1 win over Arsenal.
Sam Clucas scored twice as Swansea jumped up three spots from the bottom of the table to 17th.
The win follows the Welsh side's defeat of Liverpool a week ago and was their third victory in five league games since Carlos Carvalhal took over as manager last month.
"To win against Arsenal after beating Liverpool, I'm more than proud of my players," Carvalhal said after the game. "I told them we are ready to do something different. We have a chance (of staying up)."
Nacho Monreal gave Arsenal a first-half lead only for Clucas to equalise a minute later.
A poor clearance from Arsenal keeper Petr Cech led to Jordan Ayew putting the Swans in front in the second half and Clucas clinched the win with four minutes remaining.
Arsenal remain in sixth place, but are now eight points off the top four and Champions League qualification.
"I felt defensively we were very poor and made big mistakes," manager Arsene Wenger said. "I believe we were not good enough, I believe we were not disciplined enough."
Also on Wednesday (NZT), Liverpool tightened their hold on a top-four place with a 3-0 win at Huddersfield.
Emre Can, Roberto Firmino and Mohamed Salah scored as the Reds rebounded from consecutive losses to Swansea in the league and West Brom in the FA Cup.
"It was exactly what we needed," manager Juergen Klopp told the BBC. "It was nearly perfect - not the performance, the result."
The win lifts the Reds to level on points with Chelsea, but they sit fourth due to an inferior goal difference. Klopp's team is now five clear of fifth-placed Tottenham.
Elsewhere, West Ham and Crystal Palace each moved up in the table after drawing 1-1.
Christian Benteke headed Palace into the lead with Mark Noble equalising from the penalty spot.
West Ham climbed up to 10th, with Palace now 12th.
Second-placed Manchester United host Tottenham and West Bromwich Albion visit leaders Manchester City among Wednesday's seven games.
