3. Celtic
TEAMtalk also reported that Celtic are keeping tabs on their former player.
A move would mean a return to his boyhood club for Tierney and also a reunion with former manager Brendan Rodgers, who he previously played under with the Hoops.
It has been rumored that Arsenal is considering offers in the region of £25m, which could possibly be out of Celtic's financial reach. However, a return to his previous club may certainly be a possibility for Tierney, with his Gunners career likely over.
