I can remember Argentina 1978, where Scotland went there convinced they would win the thing. We're on the march with Ally's army! They went home after the end of the first group stage after losing 3-1 to Peru in their first game and getting a 1-1 draw with Iran in the second. Iran scored both goals. They did manage a 3-2 win over eventual finalist, the Netherlands, in the last game but then got on the plane home. I struggling to see anything different happening this time around for Scotland, or England come to that.
Here's an odd thing, at the '78 event there was a second group stage with eight team split into two groups of four, all paying one another. The team at the top of each group contested the final, there was no knockout phase.
