With Spain favourites to win the group, and Sweden also along for the ride, a win for either Poland or Slovakia in St Petersburg would stand one nation in good stead to reach the knockout stages.
Poland have not had the best run heading into the tournament, and have only made it out to the Euros knockouts once before - but they do have the best striker in world football in Robert Lewandowski. As for Slovakia, they reached the last-16 at Euro 2016, and could be dark horses.

Poland vs Slovakia is scheduled for a 5pm BST kick-off on Monday, June 14, 2021.
