Michu enhanced his ever-growing reputation with two late goals as Arsenal's worst start to a season under Arsene Wenger continued.
Spanish striker Michu struck with two minutes left, curling the ball home after a neat one-two with Luke Moore.
Nathan Dyer's persistence then sent Michu clear and another composed finish gave Wojciech Szczesny no hope.
Gervinho wasted Arsenal's best chance when he made a mess of a free header in front of goal.
The midweek draw at Everton had already given Arsene Wenger his lowest points tally at this stage of the season - 21 points from 15 games - since taking over at Arsenal 16 years ago.
There were audible groans at the Emirates and there is no doubt the current team lacks the class players needed to keep tabs with Man United, Man City and Chelsea - but being a succesful manager isn't just about winning trophies - its about creating a club that is financially stable.
The Arsenal Board have Wenger to thank for astute transfer deals over the years that has seen the Gunners rake in huge profits on the likes of Nasri, Van Persie, and Emnmanuel - in fact over the past five seasons transfer dealings alone have netted well over £40 million in profit.
Unusually for Arsenal they have actually splashed out by their standards in the last two seasons with £44 million already spent in 2012/13 on Lukas Podolski, Olivier Giroud and Santi Carzola on top of the £53 million spent in 2011/12 on the likes of Mikel Arteta, Girvinho, Alex Oxlaide-Chamberlain, Per Mertesackere and Andre Santos. But with over £112 million recouped in the same period Wenger's transfer account is very much in the black.
With the Emirates almost 100% capacity at most league games and courtesy of some of the highest ticket prices in the Premier League match day income is second only to Manchester United.
Arsenal have made significant progress in reducing the debt incurred in building the Emirates and despite their league position Wenger is in the same position as his great rival Sir Alex Ferguson - from where we sit - Wenger will decide when the time is right to go.
Unlike Man City and Chelsea, Arsenal are safely thorugh to the knock-out stages of the Champions League and that will also ensure another income boost in the later part of the season.
Man City in the last five seasons have spent over £530 million recouping just £130 million.
Things might look bad today football wise but Wenger's legacy stands him in better light than a few bad results.
