Code Orange, apparently. Code Orange? Air quality alert. Pollution central. Temperatures had just hit 32.7 degrees, a potential problem for those with respiratory conditions, for elderly folk and - we feared - for Scottish footballers and for those sweaty foot soldiers following them. Bolivia, we knew, were no great shakes. Their weak attempt to qualify for the World Cup was enough evidence of that.

Another plus. Scotland picked their moments to strike and were pretty ruthless when they did. Bolivia posed no threat. No World Cup to give them an edge, no players with much about them, no real answer to Scotland's focus. You can caveat the hell out of this if you wish - and restraint is no bad thing - but scoring the number of goals Steve Clarke's side did, creating the number of the chances they did, and adapting to the temperatures with relative ease was impressive and heartening before Haiti next Sunday (02:00 BST) live on the BBC. Haiti will be more physical , more athletic, more pacy and more threatening, but Scotland will have gained a lot of belief. On a sweltering day, they could not play at a breakneck speed, could not bring that physical intensit
