Isn't that a little ironic when compared to most other nations the British media are one of the harshest on some of their athletes. Murray has had an extremely tough time from the media and the general public because of the joke he made years ago, in a press conference, with Tim Henman, who is English.
It's not really that harsh. It's actually one of the best at glorifying mediocrity. Case in point; English national team. Also the critics of Murray from that interview were mainly casual tennis media and those who completely took the comments out of context. The proper sports media didn't really give it that much coverage.
