Argentina vs. Iceland - June 16
This is one of the most intriguing matches in the group stages, as the smallest nation in World Cup 2018 goes up against one of the biggest teams, presenting a 'David vs.Goliath' clash.
Iceland won the hearts of thousands of fans after its Cinderella run to the quarterfinals at the 2016 Euros.
Going up against one of the best attacking teams and the best player in the world, Iceland are the underdogs. But with this Iceland team, anything can happen - just ask England, who were knocked out by the tiny nation in the Euros.
This is football and anything can happen. After all, it was David who came out on top against Goliath.
