Former Rangers midfielder Nicky Law has revealed he thought his performance against ex-Celtic star Kieran Tierney in the 2016 Scottish Cup semi-final would lead to him "not being able to set foot in Glasgow again."

It was the Hoops academy graduate's first appearance against the Ibrox side and he left an impression on the ex-Motherwell man.

Rangers went on to win the fixture on penalties after Tom Rogic had equalised in extra time.

And despite the result, Law felt like Tierney had got the better of him in the match.

Speaking to the Scottish Sun, he said: "Kieran Tierney was flying at that point and I knew he was going to the very top.

"We knew we had to stop him, but he was relentless getting up and down.

"I remember Tierney skipped past me for the equaliser and I just wanted the ground to open up and swallow me.

"I thought the Rangers fans would never forgive me. I feared I wouldn't be able to set foot in Glasgow again as the game is so important."

 The Scotland international has also been urged to stay at Arsenal by Gunners hero Bacary Sagna.

Tierney has struggled to pin down a starting position at the Emirates this season after Mikel Arteta signed Oleksandr Zinchenko.

However, despite reduced game time, Sagna has backed the Celtic academy graduate to stay and fight for his place.

Speaking to the SportingPost, he said: "I wouldn't leave the club. 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."
