Ashley Cole and Samuel Eto'o have been released by Chelsea.
The contracts of the former England full-back and the Cameroon striker, both 33, expired on Monday, and neither was offered fresh terms.
"Cole has a very strong claim to be the club's greatest player of all time in his position," read a statement.
"Chelsea thanks Ashley for the fantastic service throughout his eight years here and for helping to bring so many trophies home."

One out-of-contract player who is staying, though, is goalkeeper Mark Schwarzer.
His game time may be more scarce this season, though, after the club confirmed Belgium international keeper Thibaut Courtois would return after three seasons on loan at Atletico Madrid.
The 22-year-old helped the Spanish side to the La Liga title last season, and a place in the Champions League final.
Another back-up goalkeeper, Hilario, departs after eight years at the club, as does 24-year-old defender Sam Hutchinson.
