Real Sociedad are locked in talks with Arsenal for Kieran Tierney.
La Real aim to take the fullback on-loan for the season as they prepare for their Champions League campaign.
The Sun says Gunners manager Mikel Arteta is willing to release Tierney knowing he has been frustrated with his lack of minutes since the turn of the year.
While former club Celtic are keen, La Real are the favourites to land the Scot.
Tierney has a deal with Arsenal to 2026.
