Cazorla Double Inspires Arsenal Win
Arsenal earned some respite after a turbulent week as two Santi Cazorla goals helped them beat relegation-threatened Aston Villa.
Cazorla powered in a low shot to give the hosts a sixth-minute lead.
Arsenal could not make the most of their possession and were punished when poor defending let Andreas Weimann drive in a 22-yard equaliser.
But Nacho Monreal cut the ball across for Cazorla to sidefoot in a winner from 12 yards after 85 minutes.
The victory moved Arsenal to within a point of fourth-placed rivals Tottenham and, even though it was not a convincing win, it will come as a huge relief after home defeats by Blackburn and Bayern Munich in the past seven days.
Villa will be heartbroken after a game in which they defended so resolutely after letting in the opener and were rewarded for their counter-attacking efforts when Weimann scored.
However, they could not hang on for a point as Arsenal applied some late pressure and the West Midlands side dropped into the bottom three on goal difference.
Villa next play champions Manchester City before relegation rivals Reading and QPR, while the Gunners, who will hope to improve on a laboured performance, are scheduled to play fellow top-four contenders Spurs and Everton.
Gunners midfielder Jack Wilshere had highlighted that his side have a tendency to be slow starters in matches and he made sure that was not the case this time around.
The England international was central to his side's play, surging clear from the left side in the opening minutes and having a driven shot fended away by keeper Brad Guzan.
Arsenal, though, did not have to wait long for the breakthrough as they took advantage of some hesitant and uncertain defending from a Villa side without injured centre-back Ron Vlaar.
Wilshere slipped the ball to Cazorla and, after his first shot was blocked by Nathan Baker, the Spaniard was quickest to latch on to the rebound before firing past Guzan.
The visitors responded with a tenacity to test the home side's resolve and give their hosts plenty of anxious moments.
Gabriel Agbonlahor had a shot parried away by keeper Wojciech Szczesny before the Villa forward narrowly failed to get on the end of a low Charles N'Zogbia cross across the Gunners goal.
A mistake from Monreal let the lively Weimann surge clear and the Austrian cut the ball back for N'Zogbia, whose first-time shot was well saved.
Arsenal briefly quelled Villa's threat and went close to a second when some neat passing ended with Olivier Giroud's low angled left-foot shot being saved by Guzan just before half-time.
Villa centre-back Ciaran Clark gave the home side a scare when he met an Ashley Westwood corner just after the break only to put his effort disappointingly over.
Giroud horribly sliced a shot wide at the other end and Arsenal's failure to add to their lead kept the visitors in with a shout of stealing an equaliser, which Villa duly did.
A Villa clearance was poorly headed by Gunners defender Carl Jenkinson on the halfway line and N'Zogbia nodded the ball to Weimann, who raced unchallenged at the home goal before scoring with a low strike.
Wenger's frustrations on the touchline were all too clear but his mood improved when a forward foray from Monreal let Cazorla tuck in a winner and help Arsenal avoid three successive home defeats for the first time since 2002.
