4 of those Joker v Fed head to head wins came after Feds 36th Birthday. So it's much closer (23-22) when you take peak Joker versus peak Fed.
Your GOAT is yet to win a Grand Slam without dropping a set with 22 tries.
My GOAT done that twice. And once
when beating a top 3 seed player in the final going by the name of Novak Djokovic.
I counter your mish mash of non-Grand Slam winners with Jokers mish mash of Kyrgios, Tsitsipas, Berretini, Anderson and Tsonga. As you included Cilic who won a Grand Slam I'll then have to include Medvedev who Joker handed his only Grand Slam win to.
I’ll counter your argument with a quick comparison of Slam wins after turning 29… Still in their peaks, but both playing against similar opponents as there was that short period when everyone was playing at their best and against one another. Fed 4 Slams, Djok 12….. and counting…..
Stats about dropping sets, etc are a red herring. Means nothing. Fed has had a pretty injury-free career given his effortless style and shot selection (he’s my second of all time by the way) so was able to still play near his top level up until very late into his career.
Your opponents argument is also weaker as I’ve proven that 60% of his opponents were the other top 3.
He’s played against the better opponents and for longer.
The 36 age argument makes no sense as Djok is 36 in four months himself and still showing no sign of slowing down, which tells me that you think 36 is well over peak and yet Djok is still playing at his best given he’s nearly. 36 himself.
Lastly, Fed has never beaten Nadal at the French Open while Djok has done so twice and is the only player to have beaten Nadal at all four Majors.
