Re: If Djokovic stays the No. 1 until October, he will overtake Nadal...
Then if he stays there until October 2017 he'll be ahead of Federer. He's only a bit over half to Nadal so let's not get too excited.
How about 2018, 2019?
GO Roger Federer, Nick Kyrgios, Borna Coric, Vasek Pospisil, Kei Nishikori, , Milos Raonic, Jerzy Janowicz, Grigor Dimitrov, Dennis Novikov and Bernard Tomic and Mikael Ymer
Thiem will be No 1 by Dec 2017
Nick Kyrgios will be No 1 by Sep 2018
Mikael Ymer will be No 3 by Dec 2018
Alexander Zverev will be No 3 by Dec 2017
