Kenny Miller admits the inventive football being played by Gordon Strachan's Scotland has made him regret retiring from the national team.

The Rangers frontman called time on his Dark Blues career last year after bowing out with a goal against England at Wembley.

But the 34-year-old is now pining for a return to international service after watching the slick displays put on by Strachan's men in their Euro 2016 qualifiers.

Scotland were dominant as they beat Georgia 1-0 at Ibrox before impressing again in the 2-2 draw with Poland in Warsaw.

Miller, who scored 18 times for the Scots in 69 appearances, said: "The performances were fantastic. I thought we were superb against the Poles on Tuesday night. We dominated possession against a team that had just beaten the world champions (Germany).

"The manager is infectious. He's had that effect on the squad since he's come in. We've got four points from the three games; I think it should have been more.

"I made the decision to retire last year but it's tough - I've always said I miss that side of it, miss meeting up with the lads and being part of that national team.

"At the moment I'm enjoying watching. It's fantastic to see the way the team has developed under the manager.

"Being a forward and seeing the way the play and the style of football we are playing, obviously you're looking on it with a bit envy.

"Not that it was bad in my day, just we are playing a different kind of brand now. You look on and think it would be great to play in that team, but the players we've got are more than capable."

Scotland face a crucial clash with the Republic of Ireland at Celtic Park next month and former national team assistant boss Ally McCoist admits it is a game the Scots cannot afford to lose.

The Rangers boss said: "I was thrilled by both performances. It's been an encouraging start and sets it up for the Republic game. What a game that will be.

"Is it a must-win match? Must-not-lose."
