Gary Caldwell admits Scotland require more than a change of fortune if they are to get three points in Wednesday night's crunch World Cup qualifier against Iceland.
The Scots sit third in Group 9 following Saturday's 3-0 defeat in Holland, meaning victory at Hampden Park versus Iceland is vital if they are to keep their fading hopes of reaching South Africa alive.
George Burley's side have admitted their frustrations at some debatable decisions in their recent qualifiers, but Celtic defender Caldwell is refusing to dwell on their recent disappointment.
He said: "At times, you need the odd break and so far in this campaign we haven't really had that.
"But we can't really rely on luck, we have to rely on ourselves. We haven't picked up enough points as yet and we have the opportunity on Wednesday to do that.
"We believed we could go to Holland and get three points; it didn't happen but now we have to focus and get the win to give us the chance to qualify.
"It's a game we must win and we are looking to create more opportunities than we did on Saturday. To do that, we have also to have the crowd behind us and be really positive."
