City also made an bid for the England skipper last season, but the 28-year-old is committed to the cause at Stamford Bridge.
A statement on the club’s official website said: “We can confirm we have completely rejected an offer from Manchester City for John Terry.
“It was made clear to City, for a second time following an approach last season, that we would not entertain any conversation on the subject.
“At the time John also reiterated his total commitment to Chelsea.
“We would like to make it clear, and will not do so again, that John is not for sale.”
