Regarding setting in a foreign country. No one can be sure about that of course, but I think among all the Russians who have come to England lately he should have less problems with daily life setting. For instance compared to Pavluchenko or Zhirkov (who are good players but a bit "too Russian" if you see what I mean) Bill is very sociable, friendly person - earopian type of a person I should say.
As for football specific matters. I do watch premier league. Also hard to say, but I`m positive. The important thing to understand is that Bill still has a lot in potential. He is not a "ready made" star yet who demonstrates superb performances every game, but he can be. If we take simply physical power he is probably not among the best. But you know, in Russia before Arshavin came to England a lot of people were saying he wouldn’t be able to play in English league successfully because he is not fit enough. Only with 4 goals to Liverpool these talks faded out. The same story with Dimiyar. Hard to say if he is strong enough, but he has magic in his feet when he is in his best shape.
