Neither star holds any fears for the tenacious young Celt.
He reckons that those duels with his team-mates have been ideal preparation for the match against Gareth Southgate’s outfit.
Tierney said: “You always look forward to challenging yourself against the best players.
“Raheem Sterling is a world-class player and when I played against him that night at Celtic Park it was a good battle.
“That’s what makes you a better player, testing yourself against players of that quality.
“At Celtic, I do it in training against Paddy Roberts and Scott Sinclair – they are the best, as well.
“Training against these guys every day makes me a better player.
“It’s really good preparation for these type of games when you training against the likes of Paddy.
“He’s brilliant. I don’t think he likes playing up against me because I end up just kicking him!
“No, you can see in the last few weeks that Paddy has been in the form of his life. He is a top player.
“I just thought there were too many left-backs and that I’d been moved across in training to make up a team. When I was told I’d be playing there, I was delighted to be starting, but it was a surprise to be on the other side. It was the first time I’d done that.
“As a player, it helps you to develop when you experience different positions.
