Four points should be enough to see them through and they will definitely finish in the top two of the group if they take a point or better from this game, while even defeat could see them end the day second if Switzerland are not able to win and turn around the gap in goal difference.
Italy, meanwhile, have been one of the most impressive performers at the tournament so far.
They have scored six, are yet to concede and have one of the best attacks around in terms of technique and link-play - plus the depth in the squad to change things around here if they want, resting key men for the knock-out stage.
Here’s everything you need to know ahead of the game.
