Kris Commons has no doubt it is "crunch time" in Scotland's World Cup qualifying bid.

The Scots lost 4-0 against Norway in Oslo last month to drop to third place in Group Nine with just seven points from six games.

Consequently George Burley's side face Macedonia tomorrow and Holland on Wednesday knowing six points from the two Hampden clashes are essential if they are to claim second spot in their section and a November play-off spot.

Derby winger Commons met the under-fire Scotland boss when the squad convened at Cameron House on Tuesday and is clear about what is required in the next two games.

"It was a short, sharp little meeting," said 25-year-old Commons. "It's crunch time, it's the business end of the group stage and we need to do a job. We have to be at our peak to do that job.

"When you lose a game like we did in Norway, it is disappointing and we didn't do ourselves favours in the way we went about it."

Aberdeen's Jamie Langfield was yesterday called up by Burley as cover for keeper Craig Gordon following an injury to reserve Neil Alexander.
