Arsenal came out on top in a tale of two halves at the Emirates with a 3-0 victory over flailing Bolton.
Robin Van Persie scored his 100th goal for the club, as his well-taken second-half brace settled affairs, with Bolton's David Wheater's red card proving a decisive moment.
The result brings the Gunners a much-needed clean sheet yet stretches Owen Coyle's Premier League winless streak to five games.
With less than two minutes on the clock, Arsenal's rearguard stability was already being questioned, with Wojciech Szczesny clawing away a smartly executed volley from Darren Pratley just inside the Gunners' area.
The shock seemed to startle the home side into life yet, though they were on the front foot, Bolton's two compact banks of four made it difficult for the hosts to craft genuinely threatening opportunities.
When through on goal, Gervinho's touch allowed Jussi Jaaskelainen to deny the Ivorian at his feet, while Van Persie went tantalisingly close with a curled effort from 25 yards out.
Chances were few and far between in a game that became characterised by both teams' inability to stamp their authority in the middle of the park and proceedings developed into a war of attrition.
Gervinho slammed one over the bar from range just after the half-hour mark and Laurent Koscielny acrobatically shinned one woefully off target when free in the box as the hosts pushed for an opener.
On the stroke of half-time Wheater did brilliantly to deny Van Persie after some smart work down the left by Theo Walcott, before the pacy winger then went close himself with a curling effort after cutting in from the flank that was wide by a whisker.
It took moments for Arsenal to find the breakthrough after re-emerging after the break. Aaron Ramsay fed the ball into Van Persie on the edge of the box and after going the long way round the Dutchman lashed his left-footed effort into the near post giving Jaaskelainen no chance.
Bolton's task was made all the harder 10 minutes on, as Wheater was shown a red card for hauling back Walcott when through on goal, though the Gunners livewire made the most of the minimal contact.
From there on in it was largely one-way traffic as Arsenal peppered Bolton's goal.
Jaaskelainen made a great double save to deny Van Persie before reacting brilliantly to once again deny the goalscorer as the home side's captain powered a goalbound header after the ball was stood up at the far post by Walcott.
Arsenal's lively duo were not to be denied in the 71st minute though, when Walcott fired a low cross in from the right touchline that Van Persie merely had to apply the finishing touch to and double his side's lead.
Walcott should have done better when through on goal with just Jaaskelainen to beat but Alex Song put the icing on the cake, scoring Arsenal's third with a well-taken right-footed effort from just inside the box as the home side coasted to victory.
