Arsenal's hopes of challenging for the English Premier League title took what could be a decisive blow Sunday with a 3-2 loss at newcomer Swansea.
Robin van Persie put the Gunners ahead in the fifth minute with his 18th goal of the season but Swansea outplayed and outpassed what has long been one of England's most attractive teams.
Scott Sinclair converted a 16th-minute penalty kick before Nathan Dyer made it 2-1 to the Swans 12 minutes after halftime. Theo Walcott tied it in the 69th but Arsenal conceded less than a minute later when Danny Graham took advantage of some slack defending.
Arsenal's sixth defeat in 11 road games allowed sixth-place Newcastle to draw even at 36 points with a 1-0 win over Queens Park Rangers on Leon Best's 37th-minute goal.
Arsenal is four points behind fourth-place Chelsea in the final Champions League berth. Swansea is 10th place, 10 points behind the Gunners but nine clear of the relegation zone.
"It's something we all inherently believe in and we've had success with it," Swansea manager Brendan Rodgers said after his team's first win over Arsenal in 30 years. "The players show great courage to pass the ball. Sometimes we make mistakes but I've got a great belief they can play and pass, even against the best teams."
