Kai Havertz and Ben White scored twice as Arsenal thrashed Chelsea 5-0 on Tuesday to surge ahead in the Premier League title race and ramp up the pressure on Liverpool and Manchester City.
Leandro Trossard was also on target for the Gunners, who move three points clear of Liverpool and four of Manchester City.
The destiny of the title remains in City’s hands as the defending champions have two games in hand.
Liverpool have also played one fewer game than Arsenal and are in action at Everton in the Merseyside derby on Wednesday.
However, Mikel Arteta’s men’s goal difference advantage now looks unassailable should it become decisive in the title race.
Chelsea and Arsenal’s title rivals were dealt a huge blow before kick-off as the Blues’ danger man Cole Palmer was ruled out due to illness.
Palmer has scored or assisted nearly 50 percent of Chelsea’s Premier League goals this season and his presence was badly missed by the visitors.
Despite enduring a disappointing first season under Mauricio Pochettino, Chelsea had been unbeaten in eight consecutive league games prior to their FA Cup semi-final defeat to Manchester City on Saturday.
But they were blown away by an Arsenal side keen to reaffirm their title credentials after losing their last home game to Aston Villa.
The hosts flew out of the blocks and were in front inside five minutes.
Trossard only ended up at the Emirates after Arsenal were gazumped by Chelsea in the battle to sign Mykhailo Mudryk in January 2023.
The Belgian has proved to be a far more productive signing and smashed in his 15th goal of the season at Djordje Petrovic’s near post.
