Roger Federer is coming to the end of his glittering tennis career
That is the shock claim made by his former coach Paul Dorochenko.
Federer, 36, may be coming to the end of his glittering career but he is still performing at the top of his game.
The Swiss star won the Australian Open last month and recently returned to the world No 1 spot after triumphing in the Rotterdam Open.
And Dorochenko, who coached Federer through his teenage years, believes he can continue to play into his 40's.
"For me, he can play until he is 40 without any issue," he told La Razon.

He will stop when he starts losing to more normal people
"He will stop when he starts losing to more normal people.
"He likes to win, like everyone, but he likes it more.
"Federer has this thing that the 'tops' have.
"[Zinedine] Zidane and [Michael] Jordan.
"He moves in an impressive way."
Dorochenko admits Federer could be a handful at times before he made it as a professional.
But the coach is proud to have mentored the icon through a crucial stage in his development.
"I knew he could be a great player, that's for sure, but from here to win 20 Grand Slams and I think he will win more," he added.
"The good thing for me is that I made a little part of history, and not so many people worked with him."
