Chelsea have rejected a second offer from Manchester City for captain John Terry.

The size of the offer made by City was not revealed in a statement from the Blues on Friday morning, however, the south-west London club sought to end any further interest saying they would "not entertain any conversation on the subject".

"We can confirm we have completely rejected an offer from Manchester City for John Terry," a statement on the club's website read.

The news comes as the latest rebuff for City, who have already had a bid to sign Barcelona striker Samuel Eto'o knocked back this summer.

City made an offer for the 28-year-old defender last season when they encountered similar short shrift from the Blues, who this morning reiterated the England captain's desire to stay at Stamford Bridge.

"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," continued the statement.

"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."

Meanwhile, Chelsea have boosted their goalkeeping numbers by signing Middlesbrough stopper Ross Turnbull and agreeing a new contract with Hilario.

Turnbull, 24, was out of contract at Middlesbrough and has been confirmed as a free signing on a four-year deal.

Reserve keeper Hilario, 33, has also signed a new two-year contract which will run until 2011.
