The Blues shot-stopper suffered from cramp in the dying minutes of the Carabao Cup final, with the scoreline still at 0-0.
As a result, Sarri wanted to replace him with ex-Manchester City keeper Willy Caballero, but Arrizabalaga refused to come off.
He saved one penalty in the ensuing shootout, but City ended up winning 4-3 after David Luiz and Jorginho missed their penalties.
However, Sarri downplayed the incident after the game.
"It was a misunderstanding because, by radio, I understood there was a problem and we needed a change, and I realised the situation only when the doctor arrived to the bench," the Italian tactician told Sky Sports after the match.
"So it was a big misunderstanding because I understood that the goalkeeper had cramp and was unable to go to the penalties. But it was not cramp and so he was able to go to the penalties.
"The goalkeeper understood that I asked for a change for his physical problem, and he said: 'I haven't a physical problem' and so he was right, I think.
"I realised this after when the doctor arrived to the bench and, with the keeper with a little problem, I wanted Caballero to be ready."
Sarri also insisted he will speak to the player about the substitution snub because a story like this could easily get out of control.
"I want to talk with him as he needs to understand we can get in trouble, especially with you (the media)," he added.
Chelsea will host Tottenham Hotspur at Stamford Bridge for their next fixture, and it remains to be seen whether or not Arrizabalaga will be selected in goal again.
