Kieran Tierney admits there was a moment when he wondered what he might have done leaving Celtic.
The Scotland full-back departed the Hoops for Arsenal in a £25m deal two summers ago. He has since gone on to become a regular for the Gunners, and a real fans favourite down in London.
And, as he prepares to play for Scotland in the city this evening, Tierney has been speaking about the big move in 2019.

In an interview with FourFourTwo, he said: “Glasgow and London are completely different cities. Everything was new to me.
“It was doubly difficult because I was injured when I signed and taking a bit of stick back home for leaving Celtic.
“So, you have your moments when you miss your nearest and dearest. I didn’t know my team-mates too well at that stage, so it all adds up.

“There was a flicker of ‘what have I done?’ but that passed very quickly. I love it at Arsenal and I’m well looked-after.
“Time is also a healer and my love for Celtic will never change – I hope people realise that. The decision to leave was the hardest of my life.”
Tierney is a big game player
You can’t really argue against Tierney making the right call back in 2019.
Sure, we’d have loved to see a top talent and boyhood fan stay at the club forever. But his quality always meant that he would outgrow Scottish football.
And when you consider the mess Celtic were last season, you can hardly hold it against him.

He will have plenty of Celtic fans backing him tonight as he takes on England for Scotland, hopefully from the start.
Tierney is someone who always seems to rise on the biggest stage.
Wembley, tonight, certainly fits that bill.
