Bosnian international Semir Stilic has urged Lech Poznan to sanction a move to Celtic in this month's transfer window.
The 21-year-old midfielder has been linked with a £2.5million move to the Scottish champions.
Reports suggest he is also attracting interest from Spanish outfit Espanyol but the highly-rated youngster remains keen on a switch to Celtic.
He told the Scottish Daily Mail: ''I want to leave Lech Poznan. It is an honour for me that a great club like Celtic are interested.
''I know Lech appreciate me and want me to stay. But, if Lech agree, I would like to move club now.
''I don't want to wait because I don't even know if Celtic would still want me in six months' time.''
