Arsenal delivered an emphatic warning that they remain serious title contenders as they outclassed abysmal Chelsea at Emirates Stadium to return to the top of the Premier League. The Gunners had gone four league games without a win and were heavily beaten last time out at reigning champions Manchester City, who replaced them at the summit with victory at Fulham on Sunday. Arsenal responded by producing a magnificent first-half display, racing into a 3-0 lead inside 34 minutes courtesy of two crisp strikes by captain Martin Odegaard and a scrambled finish by Gabriel Jesus. Chelsea, who fell to a sixth straight loss under interim manager Frank Lampard, were thankful to goalkeeper Kepa Arrizabalaga that the scoreline was not even more embarrassing and even pulled one back through Noni Madueke.

Arsenal, however, were never in serious danger and are now two points clear of City having played two games more than their title rivals. Arsenal answered all the questions about their character following a recent mini-slump as they tore into Chelsea from the kick-off, backed by fervent supporters who have not given up despite City’s relentless surge back to the top. The Gunners have been unfairly tagged as “chokers” by some following a recent run in which they lost two-goal leads at Liverpool and West Ham United, drew at home to struggling Southampton and were simply overwhelmed 4-1 at City. This was the Arsenal who have made an outstanding contribution to this season, made the title race a serious contest and provided a feast of attractive attacking football along the way.

Mikel Arteta’s side were assisted by a truly appalling first-half display by Chelsea, but Arsenal were nevertheless quicker, showed more intensity and ran their London rivals ragged with the quality of their play. Arsenal looked full of self-belief but they will be a little disappointed that they did not add to their tally after the break and also allowed Chelsea to give themselves the faintest glimmer of hope with a goal. There will also be concern over an injury to defender Gabriel, who struggled on after taking a knock when Madueke scored Chelsea’s consolation but eventually had to go off. In all other respects, however, this was a highly satisfactory night for Arteta and his players. Chelsea, now languishing in 12th place, are a team seemingly lacking any structure or gameplan. And supporters who hoped the chance to dent Arsenal’s title challenge in a London derby might finally fire up their under-performing stars were left feeling betrayed by another dreadful showing.
