Chelsea ran out comfortable 2-0 winners against the Gunners on Sunday at the Emirates.
According to Manchester United legend Roy Keane, Chelsea could have scored seven goals against Arsenal if the Blues really went for it in the second half.
“Very comfortable, scored two, could have been seven if they really went for it the second half,” Keane told Sky Sports.
“We saw the quality in the players, confidence, they have a swagger Chelsea, and you can see the shortcomings of Arsenal.
“There’s no hiding place, Arsenal are well short and it’s going to be a long old season for Arsenal.”
