Roger Federer's latest grand slam defeat could possibly be his most damaging, given the manner of his implosion, so is this now the beginning of the end for the great man?
Federer ahas said he is determined to bounce back, but we'd hate to see him playing on and dropping down the rankings even further - perhaps he wants to retire on top after winning another slam title just as his hero Pete Sampras did, but it's hard to see him ever getting that chance.
