Sorry to say that Stan was the first to say it aloud. He did say that 'maybe' Andy could come back, but there was a real sense that he was writing Andy off at the time. He said the same thing about Federer as well. His points were possibly valid, but sadly they did come across as a touch arrogant at the time, and of course in hindsight a little bit wrong.

Re Kevin's US citizenship, he's married to an American, went to university there, lives there, so I think it made sense for him to apply for citizenship. He sad he wouldn't be seeking to play Davis Cup for the US though.
So out of that entire article, all you got out of it was "Murray is not the player he used to be."
Understand about Kevin's citizenship now, thanks. I also live in another country (Canada) with several ties, so made complete sense to become a Canuck citizen. I also feel privileged that I was accepted into the fold of all Canuckian.
