Arsenal may see Kieran Tierney leave the club at the end of the season on a permanent basis.
Real Sociedad are pursuing a loan move for left-back Tierney before the transfer window closes.
Per The Athletic, the Spanish side are happy with a loan deal for this season to assess Tierney.
However, they would likely want a clause included that gives them an option to sign him permanently.
The source adds that Arsenal are not opposed to such a clause either, as the Gunners do not see Tierney as a long term option.
Manager Mikel Arteta prefers Oleksandr Zinchenko in that position to Tierney.
