Marco Amelia, Tika Musonda and Kevin Wright have been released by Chelsea, the official website of the Premier League has confirmed on Saturday.
Radamel Falcao and Alexandre Pato have also left the club but were not included in the official list of the Premier League.
Amelia, 34, was hoping to extend his stay at Stamford Bridge after he held talks at the end of last month but he is now free to join another club during the summer transfer window.
"My future at Chelsea? I'm negotiating with the club, I am happy with the experience I made in London," Amelia told Radio Deejay in May.
"The Premier League is becoming more and more 'Italian', I am happy [that Walter Mazzarri has joined Watford]."
