Kepa Arrizabalaga refuses furious Maurizio Sarri's instruction to be substituted (VIDEO)

Kepa Arrizabalaga was involved in a furious row with Maurizio Sarri during extra-time in the Carabao Cup Final at Wembley. The Chelsea boss wanted to bring on Willy Caballero after Arrizabalaga sat down on the pitch suffering with cramp. The Spaniard then insisted he was fine to continue with the score blank after 120 minutes. Arrizabalaga refused to leave the field and eventually won the war of words with his boss and stayed between the sticks. However, Chelsea were beaten by Manchester City on penalties.
