Saying this now, will be cheering on both to put on a good match. On one hand, England winning would be cool because, you know, it's home after all. However, I wouldn't be sad if Iceland won because, I mean, they've never got this far before. Think about how historic this would be for them; I would love that! XD
So yeah, whatever happens, here's to a good game of football... oh, and the huge task of facing France next game :V
