Dec 22 (Reuters) - The CEO of Russia's biggest lender Sberbank, German Gref, said on Friday his bank could be a candidate for further privatisation, being an attractive asset.

Russian Finance Minister Anton Siluanov said this week the Russian state could cut its shareholding in some large companies while maintaining a controlling stake, and has listed about 30 companies for possible privatisation. He did not name any. (Reporting by Alexander Marrow; Writing by Olzhas Auyezov; Editing by Jan Harvey)
