Portugal's place in the last 16 is already secure but Fernando Santos' side will know that any slip-ups against South Korea on Friday will almost certainly mean a knockout-tie against Brazil.
That should focus the minds of a Portugal side that have sound prospects of qualfying with a one hundred per cent group record. Portugal are 19/20 favourites with Betfred which is a fair bit bigger than they would have been had they needed to win this game to qualify.
South Korea, who do need to win this and hope that Ghana don't beat Uruguary, are 11/4, while the draw is the same price.
