Adnan Januzaj Reportedly Confirms He Wants To Play For England

what's wrong with that, better chance (by fractions) to win the world cup with England than Belgium.

I don't see the issue, he can become an englishman due to having access to both nationalities.

I agree. Playing for a NATIONAL TEAM is not the same as playing for a club.
Plus every player should be forced to sing national anthem at least one per year. Than I can respect if it is not your thing to sing it every time. I wouldn't do it every time my self. But if you want to play for a national team, you have to sing it at least once to show your loyalty. If you don't like text, then don't play. imo
