For Maurizio Sarri, Sunday evening was frustrating. The Chelsea manager saw his team end up on the losing side in a closely-contested final of the Carabao Cup against Manchester City. But more than the defeat, it was the attitude of Kepa Arrizabalaga which left the former Napoli head boss fuming.
A nail-biting fixture between the two teams had headed for extra time after neither of them managed to find the back of the net in 90 minutes. It was during the added 30 minutes that Kepa suffered an injury, which was presumed to be a hamstring injury.
With the penalty shootout looming, and his keeper suffering with an injury, Sarri chose to withdraw Kepa and bring his No.2 goalkeeper Willy Cabalerro. But in a strange turn of events, Kepa refused to be substituted!
Despite being advised by his teammate David Luiz, as well as the coaching staff, including Sarri, Chelsea's No.1 refused to leave the field. His eagerness to stay on the field wasn't met positively with the Chelsea staff, especially his boss, who couldn't hide his anger.
After defying his manager's orders, Kepa failed to deliver the good as his team lost in the penalty-shootout. He did manage to make one save - Leroy Sane's penalty - but could do nothing more as City won the shootout 4-3.
Facing flak for his act, not just from his team but also from the fans, the goalkeeper took to Twitter following the match and downplayed the incident.
"At no time has it been my intention to disobey the coach or any of his decisions. I think everything has been misunderstood in the heat of the final part of the match for a title. The coach thought I was not in a position to play and my intention was to express that I was in good condition to continue helping the team, while the docs that had treated me arrived at the bench to give the message. I feel the image that has been portrayed was not my intention. I have full respect for the coach and his authority," his statement on Twitter read.
