The 2018 World Cup runners-up haven't looked like their dynamic and competitive selves in the last 18 months or so, but a spirited win against Scotland reminded us all of the sheer class that evergreen skipper Luka Modric still possesses. Ironically, it's in midfield where Croatia might feel as though they can gain an edge, considering the embarrassment of riches that Spain has enjoyed in the centre of the park in the past decade and more. La Roja hit five past Slovakia in their final group game and, in truth, it could have been more. The 2010 World Champions might actually be clicking into gear and starting to resemble something of a dark horse, just at the right time too. This is a tough one to call but Spain should edge it, even if they need extra time.
