Scotland return to centre stage at last in must-win World Cup opener

Steve Clarke is ready to make the most important speech of his managerial life, a speech that a succession of Scotland managers over the last 28 largely painful years would have given anything to make.

What for so long had seemed like a pipe dream - as attainable as a lottery win - is now a reality staring Scotland in the face. After missing out on six World Cups in a row, and maybe surrendering to fatalism along the way, game day is upon us here in the United States.

We can play these games forever - the old prime ministers and presidents when Scotland were last at a World Cup, the things that are commonplace now but were not invented then, the music that was in vogue, the simplicity of the way the media was back then compared to the revolution that has happened since.

All of that stuff reflects the passage of time - more than 10,000 days - and the way things have changed. It's been a relative eternity. Sometimes, to the Tartan Army, it must have felt that days like these would never come again.

Is Shankland finally the striker Scotland have been waiting for?

We know that Clarke keeps his emotions in check most of the time, but we also know that he can be moving when he wants to be, as he was when addressing his players before the momentous Denmark game at Hampden in November, the night that electrified a nation.

All of the work is done now, all of the analysis of Haiti, all of the match strategy and the mechanisms to cope with the heat and humidity are firmly in place.
