As a Nadal fan, I see Nadal also defeated young Federer at Wimbledon 2008 and the Australian Open 2009, and has always led the H2H over Federer in outdoor hard, even in 2004-2007.
As a Djokovic fan, I think Federer was still at his peak till 2017, given his fantastic 2017, if not till 2019 given his excellent RG and WB performances.
As a Federer fan, I see Nadal only has 2 legit victories against non-old Federer in real Slams. All other matches of Federer against Djokodal are not valid, as Federer was old.
As a Sampras fan, I am so happy that Federer is being surpassed as my boy was.
As a Laver fan, I think Nadal and Djokovic cannot match Federer, because Federer has a classic gamestyle, his game is artistic, not merely effective.
