Kieran Tierney has cast doubt on his future at Arsenal.
The Scotland fullback is on-loan with Real Sociedad this season.
It's hard to say," he told the Daily Mail. "I loved my time there and I still have two years on the contract. I am very grateful to Arsenal. I don't know what's going to happen but I am absolutely loving it here.
I feel I have adapted quite well and I hope I can return the faith the club have shown. This is a very, very talented squad with world-class players and so many have come from the academy. It's an amazing story.
Coming here was easier than going to London, and that's not having a dig at Arsenal because they helped me massively.
Without the people at the club it would have been 10 times harder to adapt, but I was four years younger and moving from Scotland, it didn't matter where I went, that was going to be the hardest part.
It's an amazing thing to go to play for Arsenal but you still have your hurdles to overcome."
