Arsenal 1-2 Wigan Athletic
Goals from Franco Di Santo and Jordi Gomez helped Wigan stun Arsenal 2-1 at the Emirates to boost their survival bid.
Less than a week after their shock 1-0 win against Manchester United, Roberto Martinez's side stormed into a solid early lead thanks to two goals in a minute.
Arsenal pulled one back through Thomas Vermaelen just after 20 minutes but Wigan defended resolutely to secure the win which moves them five points clear of the relegation zone.
Arsenal remain in third spot, five points clear of Tottenham who have a game in hand.
Arsenal went close in the sixth minute when Yossi Benayoun got up to head a Bacary Sagna right-wing cross at goal but Ali Al-Habsi did well to push it over the bar.
However Wigan cleared the resulting corner and broke up the field to take the lead in the seventh minute. Gomez played the ball in for Di Santo who chipped it over the advancing Wojciech Szczesny before firing into the empty net.
Arsenal had no time to recover before finding themselves two-down when Wigan stormed up-field and, after some great skill by Victor Moses who pulled the ball back from the left by-line, Gomez fired in from close range after Szczesny saved his first effort.
Arsenal went close to pulling one back on 16 minutes but Al-Habsi again did well to tip a Benayoun header over the bar.
Arsenal's pressure did pay off in the 21st minute when Tomas Rosicky's cross from the right found Vermaelen in the centre and he powered a header past Al-Habsi.
Al-Habsi did well to beat away a Robin van Persie strike and Johan Djourou hit a volley just wide from the edge of the area, but Wigan held on until the interval.
Arsenal came out of the blocks quickly in the second half and Andre Santos had two quick goal-bound efforts blocked by Gary Caldwell with Van Persie unable to connect with the rebound from the second strike.
However, Wigan gradually restricted the Gunners' time and space inside their half of the field and almost went 3-1 up on 53 minutes when Moses got past Sagna down the left before hitting an angled drive which Szczesny saved well.
Moses had another great chance just before the hour when he was put through on goal from a long throw-in but opted to shoot early from the edge of the area which allowed Szczesny to deny him again.
