Celtic have told Chelsea that goalkeeper Craig Gordon is not for sale, Press Association Sport reports.
Chelsea have been linked with the Scotland international, who has resurrected his career with the Scottish Premiership champions after a knee injury seriously threatened to end it prematurely.
The Blues could be in the market for a new keeper as backup to Thibaut Courtois after sources told ESPN FC that Bournemouth are looking to sign Asmir Begovic.
But they were given no encouragement by Celtic, whose manager Brendan Rodgers outlined his desire to keep Gordon on Wednesday night as he said he was not surprised by Chelsea's interest.
