Hull City winger Cameron Stewart has reportedly become a target for Celtic.
Stewart has been informed by Tigers boss Steve Bruce that he can leave the KC Stadium before the end of the transfer window.
According to The Express, Celtic manager Neil Lennon is planning a £500,000 bid for the 22-year-old.
Charlton Athletic and Ipswich Town are also interested, but it has been reported that Celtic are favourites to seal the signature of the former Manchester United player.
