Mikel Merino scored the lone goal as Arsenal beat Chelsea 1-0 to move 12 points behind Premier League leaders Liverpool.
Both of these sides came into the match without their first-choice striker, with Kai Havertz ruled out for the season with a hamstring injury for Arsenal and Nicolas Jackson missing for Chelsea.
Merino's winner came in the 20th minute when he flicked on a curling corner from Martin Odegaard past a stretching Robert Sanchez.
In other matches, Manchester United defeated Leicester City 3-0 while Fulham beat Tottenham Hotspur 2-0.
Liverpool is leading the table with 70 points followed by Arsenal with 58 points, Nottingham Forest is third with 54 points while Chelsea is fourth with 49 points.
