Scotland host Belarus at Hampton Park today before traveling to Solvenia next Tuesday as the Scots hope to sneak into a Play-Off spot behind group leaders Italy to qualify for the 2006 World Cup in Germany.
KENNY MILLER: Revelation for Scotland and Wolverhampton Wanderers FC.
The Wolves striker (aged 25) has scored seven goals in just seven games for his Club and Country and it is hoped that his run will end before the Blades face Wolves at home next Saturday.
"Kenny Miller has been outstanding recently," McCall said.
"I hope he runs himself into the ground for Scotland in the next two games because we play Wolves after the international break.
"I hope he becomes a hero for Scotland, but is too shattered to come back."
