As seen in the foul and card per game stats, Croatia does not need to commit many fouls to see cards, whereas Czech Republic has a high foul count but only sees a card a game.
Croatia, meanwhile, are looking for their first points of the tournament having gone down 1-0 to England at Wembley in their opening fixture.
That was one of three defeats the Czechs suffered in qualifying, although five wins ensured they finished with 15 points, four above third-placed Kosovo.
