Chelsea goalkeeper Kepa left the footballing world shocked after appearing to defy manager Maurizio Sarri in their Carabao Cup final defeat to Manchester City.
The Spain international went down injured in the closing stages as the game headed towards the dreaded penalty shootout.
And Chelsea boss Sarri then made the bold call to hook his No 1 and put on deputy shot-stopper Willy Caballero.
However, Kepa refused to make way for the Argentina international.
Sarri was furious on the touchline, though later insisted the whole incident was a ‘misunderstanding.
But, despite that, Chelsea hero Sutton believes Kepa should never don the club’s colours again.
“That should be his last performance in a Chelsea shirt,” Sutton told BBC Radio 5 live.
“He’s a disgrace. I’ve never seen anything like it.
“If I was Sarri I would walk. You cannot be undermined. Why weren’t the players dragging Kepa off anyway?
“Kepa should be sacked, not Sarri. He’s been undermined – it’s the worst thing that can happen to a manager.”
Kepa has now spoken on the incident, insisting he did not mean to disrespect his manager.
“First of all, I have to say it was misunderstood,” said the goalkeeper.
“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.
“I don’t think it has to be the major act of this final.
“I understand we played a good level against one of the best teams in the world. We were close to winning, obviously we’re sad that we didn’t, and I think the team needs to continue playing like this, because today we’ve shown we can compete against the best teams. Among the negatives, we have to take the positives.”
