It's not the British league, but the English Premiership.
Sorry for the mistake!!!
I could say the same about italian league: we call it SERIE A, anyway if you wish understand my poor english... I will remember it when a dutch tourist ask for the Colosseo...(in English, of course) B)
I hear you. What I meant to say is, that people are often talking about England when they mean Great Britain (which also includes Scotland, Wales and Northern Ireland, of course) and the other way around.
I also meant to say that there is no British League, just an English League (in fact there are two, the Premiership and the Football League), a Scottish Premier League, a Welsh League and a Northern Irish League.
By the way, your English is OK as far as I'm concerned.
