Arsenal ended their dreadful four-game winless run by smashing a shambolic Chelsea side to keep the pressure on Manchester City in the title race.
The Gunners reclaimed top spot as they easily saw off Frank Lampard's Blues, who hit another low point. Martin Odegaard scored twice with the first 31 minutes to put the Gunners in control, with his first a wonderful strike from the edge of the box.
Just three minutes after Odegaard's second, Gabriel Jesus wrapped up the win by firing low past Kepa. Noni Madueke scored a consolation in the second half, but by then the damage had been done. Here, Mirror Football looks at five of the biggest talking points as Arsenal thrashed a dreadful Blues team.
