Turkish clubs Bursaspor and Besiktas are believed to be keen on a trio of Rangers players.
The current situation at Ibrox, with newco 'Gers set to drop out of the Scottish Premier League, has the future of a number of key players in doubt and clubs around Europe are looking to capitalise on that.
SunSport suggests that Bursaspor are looking at American midfielder Maurice Edu whilst Besiktas are showing considerable interest in Scotland goalkeeper Allan McGregor as well as defender Kirk Broadfoot.
Former St Mirren man Broadfoot has also been offered deals by Danish club FC Copenhagen and Cypriot outfit Anorthosis Famagusta.
