Paul 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. "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.
