In 10th minutes of mouthwatering London derby clash between Chelsea and Arsenal, Kai Havertz missed a glorious chance to put the host ahead.
The German star, who has finally begun to look back to his scintillating best, blazed a one-on-one chance over the crossbar after pouncing on a loose touch from defender Pablo Mari.
Meanwhile, Mikel Arteta’s men were not so wasteful when they were presented with an opportunity moments later.
Jorginho’s woeful back-pass almost ended up in the Chelsea net but was kept out by Kepa Arrizabalaga, before Pierre-Emerick Aubameyang squared to Emile Smith-Rowe to give Arsenal the lead.
Mason Mount was close to equalising but his goal-bound volley from eight yards was blocked by Rob Holding, before the England international had an effort save by Berndt Leno.
Christian Pulisic thought he had equalised after the break but his goal from a Chelsea corner was disallowed for offside. Chelsea failed to trouble the Arsenal goal until the dying stages when first Kurt Zouma and then Olivier Giroud hit the bar in stoppage time.
