Kepa refused to be substituted which caused Sarri's anger.

Manchester City managed to beat Chelsea in the Carabao Cup final with a penalty shootout after both teams played scoreless in normal time and extra time. But it was the Kepa Arrizabalaga's drama that made the headlines.

Kepa, the most expensive goalkeeper in the world after moving to Chelsea for 71 million pounds, refused to be substituted by the manager Maurizio Sarri when the match entered the penalty shootout.

Sarri wanted to substitute Kepa with Willy Caballero because Kepa suffered cramps at the end of extra time. But unexpectedly the player refused to be substituted and provoked the manager's emotions.

Kepa who refused to be substituted triggered the manager's emotions. Sarri, who felt that his authority was challenged by the player, was angry and showed his frustration at the edge of the pitch.

Kepa continued to play and Chelsea lost the penalty shootout. After the match, Sarri announced that the incident was a misunderstanding. Sarri thought that Kepa was not fit due to cramps, but the player said that he was physically fit and did not need to be substituted. But the manager only found out after the team doctors approached him and conveyed the condition of the goalkeeper.

But according to former Chelsea captain John Terry it was just an excuse made by Sarri to protect his players. After this incident, Kepa should not play again. But the club certainly does not want the huge funds they have spent on Kepa to be in vain, so the player needs to be protected.

Kepa's attitude clearly didn't show his class as a professional player who should be ready to follow the direction of the manager anytime, and Chelsea will have difficulty playing him back without punishing him first. But on the other hand, this incident showed the face of a 'rebellion' in the club against the manager whose future is already uncertain at Chelsea.

One thing is for sure, Kepa was embarrassing himself by doing that and he will regret it forever. No matter how good a player is, there is no player so great he can defy manager's order.
