Nah, they aren't that big of a favorite. As Trofo said, initially it was 50-50, currently it's 1.75 on Spain on Supersport.
Considering that we're playing at home, I still feel that it's 50-50. You lose with a draw though, which happens in waterpolo more and more and which might be something both teams would be happy with if the game is tied near the end.
Oh, you are right... I never thought about it. So I guess that Trofo has more chance to win this point. I hope that the fans will give some extra push tu Croatia that they manage to win in the end.
