Arsenal's Tierney joins Real Sociedad on season-long loan deal

Real Sociedad signed Arsenal left-back Kieran Tierney on loan for the season on Sunday.

The 26-year-old Scotland international joined the Gunners from Celtic in 2019 but fell out of favour behind Oleksandr Zinchenko and new signing Jurrien Timber, who is now injured.

"Playing in the Champions League is an incentive for any footballer," Tierney told Real Sociedad TV.

"(Playing in La Liga) is a change for me, but I was looking forward to it. I'm passionate about challenges and I'm thrilled to be here."
