Should tournament debutants Iceland reach the knockout stages of Euro 2016 by securing the result they need against Austria today, much credit will go to a dentist and a film director.Iceland, with a population of about 330,000, are the smallest country ever to qualify for the Euros, yet have been undaunted by their casting as minnows, holding Portugal and Hungary to 1-1 draws in Group F through resilient displays. That means a win, or perhaps another draw, against Austria, will put Iceland into the knock-out stages, a fairytale outcome which could make for an excellent movie script.Elsewhere, poor finishing means Portugal go into today's Group F match against Hungary in third place and a distinctly uncomfortable position. Only a win over the unbeaten Hungarians will take them into the last 16 without depending on other matches. Hungary, meanwhile, need a draw to make sure of a top-two finish although even if they lose they could qualify as one of the four best third-placed teams.
