Gordon came in to win his 56th cap as Scotland in a victory that takes Steve Clarke’s side into second place in Group F. Tierney, with three assists, was the star of the show alongside John McGinn, who grabbed a double to take his Scotland goals tally into double figures.
Gordon was also on hand to make a fingertip save to prevent Brandur Hendriksson equalising for the visitors soon after McGinn had given Scotland a seventh minute leader.
Tierney provided the cut-back for that goal and crossed for McGinn’s second – a header – seven minutes after half-time. Tierney also passed for Che Adams although the striker still had a lot of work to do score his first goal for Scotland. The Arsenal player was also the star man in Scotland’s previous two draw against Israel and Austria.
“I thought he was incredible and he has taken his game on even further,” said Gordon. “He talks so highly of the Arsenal coaching staff and how they have helped develop him.
“For us, over the three games he has been excellent if not the standout in every single one. He has been magnificent and hopefully we can keep him fit and playing at this level.
“I think he is world class, I really do,” he added. “He is so consistent as well and that is what makes him so good. He is doing it in every game and he's a big for us on and off the park. He is also in charge of the music and he is great for the camp and a real valued member of the squad.
“He has been more consistent and tactically and technically he has improved, playing against better players week in, week out,” he added. “He has raised his level because of that. I have seen him come through from 17 to where he is now and he will only continue to get better.”
