Chelsea boss Thomas Tuchel stormed out of his post-match interview after giving a strange excuse for the defeat to Arsenal on Wednesday night.
The Blues had twice fought back from going a goal down in the first half, but were unable to recover after the break.
A double from Eddie Nketiah, coupled with Emile Smith Rowe's strike and Bukayo Saka's late penalty were enough to claim all three points for the Gunners.
