5. Kepa Arrizabalaga
It was 2019 and Chelsea played Manchester City in the Carabao Cup Final. The game was on the edge of a knife when Chelsea manager Maurizio Sarri decided to make a substitution. He wanted to bring on the Argentine goalkeeper Willy Cabellero, to replace first-choice starter Kepa, because the former was a penalty shootout specialist. However, Kepa didn’t appreciate this.

The Spaniard refused to leave the field and left his manager apoplectic on the sidelines. The scene was unprecedented as the coach stormed down the tunnel toward the dressing room before reappearing. Meanwhile, Chelsea lost the eventual penalty shootout 4-3. Kepa received a lot of abuse after throwing one of the most infamous tantrums in Premier League history.
