Alex Lacazette and Laurent Koscielny both found the back of the net to ensure Arsenal took all three points from the game at the Emirates Stadium.
The Gunners had lost four of their last eight matches, while Chelsea had only registered victories in four out of seven games. Had Arsenal lost the game, they would be seven points behind Chelsea in the rankings.
Arsenal’s first goal should have come in the 4th minute when Bellerin played in Lacazette who then crossed the ball to Aubameyang, but the former Dortmund striker failed to capitalize on the chance. Few moments later, Sokratis headed wide from close range.
Koscielny was next to come close, connecting to a free kick by Lucas Torreira but Chelsea goalkeeper Kepa Arrizbalaga pushed his header over the bar.
However, before the next minute, Arsenal’s efforts was rewarded after Hector Bellerin found Lacazette in the area, his brilliant first touch set him up, then he squeezed his shot into the top corner. Aubamayang came close again before Pedro almost equalized for Chelsea.
Aubameyang nearly made it 2-0 for Arsenal with an overhead kick, but moments later Koscienly rose highest to meet a ball from Sokratis, diverting the ball into the net. Chelsea came close to scoring before the break but Marcos Alonso’s effort hit the post.
After the break, both teams threatened themselves, with Hector Bellerin and Sead Kolasinac causing serious problems from the full-back positions. However Bellerin was later stretched out in serious discomfort after sustaining a serious injury.
The Blues continued to fight hard, but Arsenal stood firm to ensure they took all three points from the game.
