Chelsea manager Graham Potter was involved in a touchline bust-up with Arsenal boss Mikel Arteta following a challenge from Marc Cucurella on Bukayo Saka.
The £65million summer signing went in for a challenge on Saka in the first-half which resulted in tensions boiling over in the dugouts. Referee Michael Oliver refused to give a free-kick with Arteta visibly enraged by the decision, whilst Potter felt Saka went down too easily.
Michael Oliver has been criticised by both sets of fans on social media after his refereeing performance with players on both teams getting frustrated with the stop-start nature of the match. Potter admitted that the Gunners deserved their win on the day and was critical of his own team's performance claiming Chelsea lacked 'fluidity'.
