Celtic have reportedly turned down a bid from Rubin Kazan for Korean star Ki Sung-Yueng.
Ki joined Celtic from FC Seoul in January 2010 and has several reported admirers, as he helped the Bhoys win the SPL title last season.
The bid is reported to be in excess of £6m with Celtic prepared for an improved offer in the future, according to Sky Sports News.
When linked with Tottenham Hotspur last month, Ki insisted that he was not looking to move, and has been expected to discuss a new contract.
