One of the most bizarre moments in recent football history happened during the 2019 Carabao Cup final between Manchester City and Chelsea.
Just in case you needed reminding, with the scores at 0-0, 30 minutes into extra-time, Spanish shot-stopper Kepa Arizzabalaga seemed to have taken a knock. This prompted a response from Sarri, who got his substitute goalkeeper Willy Caballero ready to come on for him, but Kepa refused to come off with penalties looming.
After a few minutes of confusion and Sarri shouting at his number one, Kepa got his way and stayed on the pitch. Sarri then stormed off down the tunnel in dismay having lost the war of words with his own player. Chelsea went on to lose on penalties 4-3, with Kepa not even coming close to saving one of City's penalties.
It was scenes we've never seen before in English football, never mind in a cup final.
