The home side was rarely threatened by its relegation-threatened visitors and cruised to a comfortable victory, while the Royals remain isolated at the foot of the leagueArsenal gave its Champions League qualification hopes a boost with a comfortable 4-1 win over relegation-threatened Reading.
New Royals boss Nigel Adkins saw his side totally outplayed throughout, and goals from Gervinho, Santi Cazorla, Olivier Giroud and Mikel Arteta ensured all three points for the home side, although there was some cheer for the Berkshire side when Hal Robson-Kanu headed home a second-half consolation.
The home side started the game brightly and it came of little surprise when it opened the scoring after just 10 minutes when Gervinho tapped home from close range.
The Ivorian started the move by driving towards the penalty area from a right-wing position before the ball eventually found its way to Santi Cazorla on the left and his driven cross was stroked home from the edge of the six-yard box by the unmarked Gervinho.
The home side should have been given the chance to double the lead from the penalty spot eight minutes later when Royals keeper Stuart Taylor clattered into Olivier Giroud, however, referee Chris Foy was unmoved, much to the bemusement of the majority of the Emirates Stadium crowd.
These two sides had scored a combined 19 goals in their two previous meetings this season, and a high-scoring affair looked likely once again as the Gunners piled the pressure on their visitors, but despite creating numerous chances throughout the first half, they were unable to extend their single goal advantage.
Just two minutes into the second half, however, Arsenal did finally manage to double the lead as Cazorla neatly stroked home from the edge of the penalty area.
Gervinho was involved once again, with the Ivorian taking on several defenders just inside the box before looking up and picking out the unmarked Spaniard who calmly curled an effort just inside Taylor’s post.
Arsenal finally killed off Adkins’ men when Giroud slotted home a Gervinho through ball from the edge of the six-yard box.
Just a minute later, however, and Reading must have sensed that another of its fabled comebacks was on the cards when Hal Robson-Kanu bravely threw himself at a Jobi McAnuff cross to head home at the far post.
The comeback failed to materialize though, when the Gunners were awarded a penalty 10 minutes from time after Adrian Mariappa fouled substitute Oxlade-Chamberlain. Mikel Arteta stepped up to hammer the penalty into the corner of the net and seal the routine victory.
