Saying you will support anyone who plays against England, is the same as saying you will support anyone that plays against blacks. Think about it. Saying "I'm Scottish but I don't mind the English" is like saying, "I'm black but I think brown people are alright". It's not really something to be proud of, it's kinda expected of you.
England have failed every time they have had to mix it with a big nation. There is a difference this time, rather than just having good players, they now have SOME great players, and a great manager. Even though, so do Spain, Germany, Portugal, Brazil, Argentina (well, maybe not a great manager) and Italy. They at least have a chance but will need to turn it on against some top teams. I want them to do well but, I want the best team to win.
For the record, I'm a walker, but wheelchairs are alright in my book. I'm sooo sound.
