The Gunners have completed the double over the Blues for the first time in 17 years to keep alive their own hopes of playing European football next season
Arsenal’s only goal came in the first half after a terrible mistake by Jorginho. The midfielder misjudged a pass back that was in a deadly zone before Kepa Arrizabalaga tried to steer the ball away but only to land right into Pierre-Emerick Aubameyang, who gave a calculated pass for Smith Rowe to slot in.
Chelsea dominated there after as Mason Mount went close twice, seeing a volley inside the box blocked before the England international drew a good save out of Bernd Leno.
Christian Pulisic equaliser on the hour was ruled out by the video assistant referee for offside, while substitute Olivier Giroud did not capitalise on a mistake made by Mohamed Elneny as he swung wildly at his shot.
The hosts then attempted twice to rescue a point in stoppage time as Leno pushed Kurt Zouma’s header onto the bar before Giroud’s volley also bounced back off the woodwork, hence Arsenal holding on to the three points..
Chelsea are fourth with 64 points, six ahead of West Ham and seven ahead of Liverpool, who have two games in hand with the blues .
Arsenal, however, are eighth and just one point behind Tottenham in seventh, although have played a game more.
