Arsenal trounced Chelsea 5-0 in a Premier League showdown at the Emirates Stadium.
Kai Havertz, the former Chelsea player who made headlines with his £65 million move to Arsenal last summer, returned to haunt his old club by netting two goals.
The evening began with an early lead for Arsenal as Leandro Trossard found the back of the net.
However, it was in the second half that the Gunners truly unleashed their firepower.
Havertz, with his precise finishing, showed why Arsenal invested heavily in him, scoring two crucial goals against his former team.
Adding to Chelsea's misery, defender Ben White stepped up with a brace of his own, further extending Arsenal's lead.
The absence of key player Cole Palmer seemed to weigh heavily on Chelsea as they struggled to contain Arsenal's relentless attacks.
The victory not only solidified Arsenal's position at the top of the Premier League table but also sent a clear message to their title rivals.
After the completion of the match, Arsenal's playmaker, Martin Odegaard was named the man of the match after his brilliant performance against Chelsea.
