This could be one of the more dynamic and entertaining groups of the World Cup.
Group D might also be one of the hardest groups for a favorite like Argentina to navigate. Croatia and their Real Madrid stars are familiar with Messi and solid defensively, Iceland are the people’s champions making their debuts, and then Nigeria might just counter attack their way into the knockouts with the young strikers they have up front.
Why do we call this a “primer” and not a preview? Because this is more a lot of key information in one place that I think is a handy reference for viewers rather than a ton of specific analysis on what each team can or could do at the World Cup.
