Arsenal returned to the top of the Premier League on Tuesday with a 3-1 win over a woeful Chelsea, set on their way by two goals from Martin Odegaard.
Arsenal raced into a 3-0 half-time lead when captain Odegaard was given acres of space - twice - by Chelsea's flimsy defence to score in the 18th and 31st minutes, and Gabriel Jesus converted from close-range 11 minutes before the break.
Chelsea, who lost for the sixth time in six games under interim coach Frank Lampard, at least managed to score only their second goal in eight games when Noni Madueke squeezed the ball past Aaron Ramsdale in the 65th minute.
