Brendan Rodgers confirmed Celtic have received an offer from Chelsea for Craig Gordon but remains adamant that his keeper is not for sale.
The Stamford Bridge club are looking to line up a replacement should Asmir Begovic, No. 2 to Thibaut Courtois, move to Bournemouth.
Chelsea reportedly bid around £3 million for the 34-year-old Scotland keeper, but speaking at Celtic's Lennoxtown training complex, Rodgers said: "There has been an offer but nothing that we would [make us] even think about moving him.
"He is a player very much part of what we want to do. He has 18 months left on his contract and I want to keep him here to build a team around.
