Assuming Hungary won't be getting any change out of their fixtures, the "mini group" in with them of Portugal, Germany, and France might throw up some drama.
With 24 teams the standout fixtures are fewer in the group stages but I'm interested to see how Belgium get on against potentially tricky ties against Russia and Denmark, and I reckon the opener, Turkey vs Italy, might be a cracking start to the tourney.
But the knockout rounds is where it's going to get really spicy.
