Current odds on skybet:
Ivory Coast 125/1
You can get better odds almost everywhere else but that gives you the idea. Spain at 13/2 looks the best bet to me. A lot of people seem to think tiki-taka has been solved but I'm not convinced many international teams can deal with it, especially not in that heat and with an actual striker this time.
Argentina are an OK bet too considering it's their home continent, they have a lot of brilliant players and the coach seems to have it together for once.
