Outclassed Chelsea squandered a series of chances, with Nicolas Jackson particularly culpable, as they suffered a first defeat in nine top-flight games
Kai Havertz scored twice against his former club as Arsenal tightened their grip on top spot in the Premier League by denting Chelsea’s European aspirations with a thumping 5-0 win.
Gunners forward Havertz, who made a £65million switch from Stamford Bridge last summer, registered two of four second-half goals on a remarkable evening at a jubilant Emirates Stadium.
Defender Ben White also claimed a brace for Mikel Arteta’s title-chasing side, adding to Leandro Trossard’s early opener, as the Blues’ recent resurgence floundered in embarrassing fashion in the absence of key man Cole Palmer.
Victory moved Arsenal three points ahead of second-placed Liverpool having now played one game more, while reigning champions Manchester City sit four points behind with two matches in hand.
Outclassed Chelsea squandered a series of chances, with Nicolas Jackson particularly culpable, as they suffered a first defeat in nine top-flight games and missed the chance to climb to seventh.
Mauricio Pochettino’s men made the short trip across the capital on the back of a painful FA Cup semi-final defeat to Pep Guardiola’s City and without 20-goal top scorer Palmer due to illness.
Blues academy graduate Alfie Gilchrist was handed a first Premier League start as part of four changes, while Arsenal recalled Takehiro Tomiyasu and Thomas Partey.
The Gunners, who suffered a damaging 2-0 loss to Aston Villa in their last home game before exiting the Champions League at the hands of Bayern Munich, began brightly and led inside four minutes.
Declan Rice was afforded time and space to advance deep into opposition territory before slipping in Trossard to escape Gilchrist and fire a low left-footed shot from a tight angle which was allowed to squirm home by Blues goalkeeper Djordje Petrovic.
Chelsea’s evening could quickly have gone downhill but Jackson avoided a potential eighth-minute red card after catching Tomiyasu’s ankle with his studs.
Arsenal, whose players wore black armbands following the death last week of former club chairman Sir Chips Keswick at the age of 84, continued to be the dominant force.
