Former Arsenal defender Bacary Sagna has urged Kieran Tierney to stay.

The Scotland left-back is a target for Newcastle and Manchester City.

But Sagna told Sportingpost: "I wouldn't leave the club," he told sportingpost.com.

“He needs to fight to play and come back into the manager's plan. He is part of what's becoming one of the best clubs in England, so where is he going to go?

“Of course you want to be able to play but sometimes you need to be out of your comfort zone, and he's out of his comfort zone now. So it's time to fight, not just leave and give up.

"What's the point of going somewhere where you know that you're going to start no matter what, and you're going to play - you're not going to progress in that environment.

“I had the same choice when I left Arsenal, because I was playing in a comfortable position. I could have stayed and yes, I was playing. But at some point, if you want to try and get better and you want to challenge yourself, you need to be out of your comfort zone.

"Zinechenko is giving him a challenge to fight for his place, so he has to train harder and get back to his very best level so he gets his opportunity and then he has to take it. If he does that he won't be spending so much time on the bench."
