GRAHAM POTTER and Mikel Arteta had a fiery exchange on the Stamford Bridge touchline after a coming together between Bukayo Saka and Marc Cucurella.
Chelsea left-back Cucurella struggled with the pace and sharpness of Arsenal’s talisman during the first-half of the London derby.

And just before the break he was marshalled off the ball and went down, protesting a foul.
Michael Oliver waved play on, sparking a furious reaction from Gunners boss Arteta, while Potter fumed that Saka had dived.
