The Scotland international will almost certainly sign with the Turkish Super Lig club for a whopping £50,000 a week and told SunSport that he was on his way to Bursa to put pen to a contract.
"I have travelled to Turkey to talk to the people at Bursaspor," he said.
"Nothing has been finalised yet as I understand they have not yet agreed a fee with Rangers.
"But the fact I have come here shows we're close.
"I played against Bursaspor in the Champions League and got a good feeling about the club.
"We'll see what develops in the next 24 hours but this could be a huge move for me. All being well I'm here to sign."
