Kepa's refusal to come off the pitch in the Carabao Cup final is going to be a talking point for a long time to come.
The Spanish goalkeeper was suffering with cramp in the final minutes of Chelsea's game against Manchester City.
Maurizio Sarri seemed concerned by his goalkeeper's injury and decided he would replace him with Willy Caballero.
But Kepa refused to come off the pitch, leaving Maurizio Sarri fuming.
Kepa stayed in goal for the penalty shootout but he could not prevent City winning 4-3.
Watch the moment below:
Kepa has come under huge criticism for his behaviour, with former Chelsea striker Chris Sutton even saying he should be sacked.
But what does Kepa make of the incident?
The Spanish goalkeeper has finally spoken out on his behaviour, and he has insisted it was never his intention to disrespect his manager.
"I have to say it was misunderstood," he said, per ESPN. "In no moment was it my intention to disobey, or anything like that with the boss.
"Just that it was misunderstood, because I had been attended to by the medics twice, and he thought that I wasn't in condition to continue.
"It was two or three minutes of confusion until the medics got to the bench, and they explained everything well. This was nothing to do with the problems I had this week, with [hamstring].
"It wasn't that. And, well, it was misunderstood. Because he thought I couldn't continue, and -- fundamentally -- I was trying to say that physically I was fine.
"I know if you see it from outside, I don't know how it went out, it is not the best image. I have spoken with the boss. I think it was misunderstood.
"I understand that on television, on social media, they're talking about this but I am here to explain it, to say that it wasn't my intention to go against the manager.
"We have spoken now, and I was only trying to say I'm fine. He thought I wasn't fine. It was in tense moments, with a lot happening..."
