Many fans assumed it was the club’s decision to let him go when it was announced Willy Caballero would leave as a free agent.
The 39-year-old was one of the seven players released by the Blues in June, alongside the likes of Marco van Ginkel and fellow goalkeeper Jamal Blackman.
However, Caballero has revealed he made the decision not to sign a new Chelsea contract.
Explaining his decision, Caballero told Goal: “Some people didn’t understand why I turned down a contract as a third goalkeeper.
“I believe I am playing at this age because I have always been motivated.
“As a third goalkeeper last season, I found it really tough.
“It was my first season as a third-choice goalkeeper. I was losing my motivation at Chelsea.
“I believe for this reason to not renew with Chelsea, to try to find a new challenge to keep that passion alive inside.”
Following the exit of Caballero, the Blues signed former Fulham goalkeeper Marcus Bettinelli as his replacement.
“I want to keep playing and living football. I am waiting for the new challenge,” he added.
“Training at Chelsea with Mendy and Kepa [Arrizabalaga] last season was very good.
“It is a challenge to train with good, young goalkeepers. I feel it was a real achievement to train at their level every week.
“I know I have just one, two, or three years until the end of my career.”
