Location of David Haye versus Vitali Klitschko?

There has been talk of a potential clash between WBC heavyweight champion of the world Vitali Klitschko and former WBA heavyweight world champion David Haye. Vitali Klitschko has got a higher knockouts to fights ratio than any world champion in history so the chances of Vitali inflicting Haye's first ever KO in the heavyweight division are quite high, but conversely Haye loves to fight slower fighters. Either way, where do you guys think any fight between the two men should take place? It'd make a change for the English, even though I don't like them, to be given a chance to see their own man fight in England for once, instead of Germany or the United States.
