Scotland head into their 'Battle of Britain' clash against Wales on Friday [Saturday morning Australian time] as narrow favourites in what is the highlight of another huge round of 2014 World Cup qualifiers throughout Europe.
The qualifying campaign might only be two matches old but already it is crunch time for both Wales and Scotland, with the loser of their meeting almost certain to yet again miss out on the world's biggest sporting event.
The two countries are already up against it in Group A, where Serbia, Belgium and Croatia all have four points after two matches.
Scotland have two points, Macedonia are on one and Wales have lost both games, with only the top team certain to make it to Brazil 2014.
And even though Wales are at home, Scotland will go in as slight favourites at $2.72 at Betfair, with the hosts at $2.92 and the draw appearing great value at $3.35.

In Group B, four-time World Cup winners Italy should extend their lead at the top and are $1.40 favourites at Betfair to win away to lowly Armenia at $11.
Second-placed Bulgaria faces a tough home game against Denmark, who are favourites at $2.56 with the home side at $3.10.
In Group C, the big clash is the Republic of Ireland hosting three-time World Cup winners Germany, with both teams unbeaten so far in qualifying.
However, Ireland are being given little hope of pulling off a repeat of their famous last-minute draw against Germany at the 2002 World Cup, with the visitors the dominant $1.46 favourites at Betfair. The draw is at $4.80 with Ireland at $9.
Group D, meanwhile, is shaping as one of the toughest to predict, with Romania and the Netherlands on six points and Hungary and Turkey both on three after two matches.
The Netherlands will almost certainly make it three from three when they host Andorra, who are winless so far.
The home nation are the shortest-priced favourites of the day at $1.01, while Andorra are an incredible $270 at Betfair, with even the draw at $85.
In Group F, the two heavyweights of the group in Russia and Portugal - both of which already have a five-point lead over their four rivals and look certain to fight it out for top spot - meet, with Paulo Bento's men slight favourites to win away at $2.78.
England, meanwhile, have a certain three points looming in Group H and are the $1.01 favourites to beat minnows San Marino at $330.
Victory would move the Three Lions to the top of the group, with fellow leaders in Poland and Montenegro not in action on Friday.
