Haven't we seen it before? No way, they aren't.
Nadal is an eternal favourite at RG and among title contenders at remaining slams (as we saw this year). He'll try his best to equal Fed.
Federer is a big contender at Wimbledon and also has chances at the AO. Make no mistake, he'll aim at #21 next year.
Federer and Nadal have been "done winning slams" since the end of 2014 now. If one thing history should tell us is that we should never underestimate these great champions. I'll only rule them out winning another slam after they hang the racquet up for good.
Maybe, but they will make at least five slam finals more, combined, and their finals W/L ratio for the last three seasons (12 majors) is 5/2 and 3/1 respectively i.e. 8 wins in 11 finals, that is 2/3 of the slams won, with only two slam finals without either Nadal or Federer therein.
This prediction comes up after every bad loss of either of them. Obviously, at some point they will have won their last slam, and the prediction will come true. I personally don't believe that they will win many more slams (as I have mentioned already in some other threads), but they have surprised us so many times, that we better don't rule them out until they retired for good.
Every year somewone has a brilhiant idea and post s thread like this. Some use got lucky in 2015 and 2016. But other then that they fail.
Federer still is a contender in Wimby. And Rafa is almost a lock for RG Final. Of course if healthy.
Winning a Slam is something only the big3 know how to do. Murray,Stan, Cilic and Del Potro have done it but its been hard to repeat.
The new guys have the talent and have beaten the big 3 but in a slam is going to be hard. If not in 2020, 2021 will definitly see this shift you are talking about.
