Craig Levein says Scotland’s World Cup qualifying match against Macedonia tomorrow is a must-win game after watching his side being held to a goalless draw by Serbia at Hampden.

The Scots failed to get their Group A campaign off to a flying start on Saturday as they struggled to find a way past Sinisa Mihajlovic’s side.

Levein’s side face tough matches against Croatia and Belgium later on in the qualification campaign and the Scotland boss admitted his side were now under pressure to take all three points against Macedonia at Hampden.

However, Levein insisted his side would not be so wasteful in front of goal again.

“It probably is a must-win match. It would certainly be beneficial to win the game.

“But, I am more confident now than I was before the match because after that game I am disappointed we didn’t win because of the chances we created,” Levein said.

“I look at the opportunities we had to hit Serbia in the areas where we knew they were weak and I could count half a dozen times where we didn’t play almost a simple pass at times to put people in on goal.

“That won’t happen again. Our guys will improve on that regard and that gives me encouragement that we are going to be better on Tuesday.”

Against Serbia chances were few and far between in a cagey first half but Scotland had goalkeeper Allan McGregor to thank early on in the match when he stopped Aleksandar Kolarov’s free-kick sneaking in while Vladimir Stojkovic blocked a Robert Snodgrass effort on goal.

While admitting he was disappointed with the draw, Levein insisted his side deserved to win the match.

“We did enough to win the game on Saturday but we just didn’t score a goal. Even when then they had spells of pressure I didn’t feel like we were going to lose a goal,” the Scotland boss said.

“I thought we defended really well and the question was could we get a goal. I think on the evidence of some of our players performances’ we deserved it but we didn’t get it.”
