Rangers-linked Ross Barkley is available on a free transfer after his contract at Chelsea was terminated by mutual consent.
Ange Postecoglou and his Celtic side were suggested as a possible destination earlier in the summer transfer window for the England international but Giovanni van Bronckhorst has now been credited with an interest according to reports.
The Sun's Alan Nixon claims the Light Blues want to snap up the experienced midfielder - who has turned out for the likes of Everton and Aston Villa - as they look to boost their ranks ahead of their assault on the Champions League. The Ibrox side will come up against Liverpool, Ajax and Napoli in their section and kick-off the campaign away in Amsterdam next week. Playmaker Barkley, capped 33 times by England, is now available on a free following his Chelsea exit with plenty of clubs no doubt ready to throw their hat in the ring for his services. The 28-year-old is on the search for regular first team football and that could be offered by Rangers on top of playing at the top level of club football.
