Image source, SNSPaul Lambert believes Scotland "100%" need a victory in their opening World Cup fixture against Haiti as "three points can take you through".
Steve Clarke's side have travelled to the US and will play one more warm-up match against Bolivia in New Jersey on Saturday before taking on Haiti in their Group C opener on 14 June in Massachusetts.
Games against Morocco and Brazil follow.
"It'll depend on what system Stevie goes with, whether he goes with the two lads up front or he changes it," Lambert told BBC Radio Scotland.
"Whatever system is going to get a result for us, we 100% need that result, regardless of how we do it, because the second and third games are going to be a little bit more difficult. He's going to have to get it right.
"The way the format is and the way the draw's favoured us, three points can take you through. That might just be enough depending on what happens in other groups. Four points will definitely get you through.
"If we can just win that first game, I think that's the key to it. You could score in the last minute and just get that win and that sets you up for everything else."
Teenage midfielder Tyler Fletcher has been called up to replace the injured Billy Gilmour, who picked up a knee knock in Saturday's 4-1 win over Curacao at Hampden.
"Somebody else's loss is somebody else's gain and Stevie's obviously thought the lad Fletcher's better than anybody to put him in at the minute," said Lambert, a midfielder who played in Scotland's last World Cup finals campaign in 1998.
"I just don't think it'll be his ability, I think it'll be what he's like off the field and how he interacts with people and how he holds himself in front of the more experienced lads. Doesn't really surprise me, that.
"I'm not sure Gilmour would've been a starter. He's done well in certain games he's been in but I don't know if he would've been a starter, even though he's a really good player.
"Stevie will know exactly what he's going to do. He'll know his team for that first game. I'm pretty sure he'll know his team that's going to start."
