#2. Argentina–Iceland (Group D, 16 June)
After managing to scrape through in their last match, thanks to captain Lionel Messi, Argentina have a lot to prove in their opening fixture. Iceland will be playing their first ever World Cup match, after they became the lowest-populated nation to ever qualify for a World Cup. After topping their qualifiers group, and knocking England out of UEFA Euro in 2016, Aron Gunnarsson and his fellows teammates are a team to reckon with. Of course, Iceland's special fans and their Viking-styled cheering in unison is a sensory delight!
This will be the first time these two teams play each other in history. Group D is the closest to a 'group of death' in this World Cup, Nigeria and Croatia being the other two teams. A victory will be essential for both teams, and it will be interesting to see in what form and spirit Messi and the rest of La Albiceleste open their World Cup.
