Kieran Tierney could land former club Celtic a tasty sell-on fee as he is linked with a move to Real Madrid from Arsenal.
The 24-year-old from Muirhouse has been a star performer since leaving Parkhead for the Gunners in 2019 in a deal worth an initial £25 million fee.
It has put him on the radar of one of the world's biggest clubs, who want him to compete with current left-back Ferland Mendy for a starting spot.
