Federer said he did not mention the mononucleosis until now because he did not want to detract from victories by Djokovic or Murray. But Federer was still criticized in the British news media for being uncharitable in defeat after he commented in Dubai that Murray had not changed his game in the past two years and was surprised at how defensively he was playing.

Federer, who said he has now learned the English term “sour grapes,” said he was trying only to provide “constructive criticism” and did not mean to imply that he did not respect Murray’s game.

“He beat me after all,” Federer said. “It’s unfortunate, because that’s not what I meant at all.”

He added: “I’ve always thought he was one of the most talented ones of the whole group, even more talented than Djokovic to be honest. I thought he would do the most first before Djokovic, but Djokovic played really well the last year and started this year unbelievably.”

I don't think he will. Well, unless he draws Murray in every tournament

Mononucleosis or glandular fever is a viral infection and does not get better with antibiotics (though obviously any extra bacterial infections would be helped) It can have a long, long drain on energy - easily six months or even longer!

  My daughter was off school for 3 months with it...so it maybe Fed's tennis

 has not become quite as vulnerable as we have been thinking.

I have had a throat infection for about 7 weeks! I've had 5 courses of Antibiotics, and its not getting rid of it. Perhaps I've got that???

Doctors are idiots!
