Dude Medvedev is 25 just won a slam and has been in 3 slam finals , he is the number 2 in the world and is possibly better on hard courts than even Novak now , do you really think he is done ?Honestly do you honestly think Medvedev wins a slam again? Zverev? Tsitsipas?
Inagree rafa and Roger are way past it but honestly id fancy them against Next agen at all majors if theybcan move ok .
Zverev pushed Novak hard in the last 2 slams they played , Novak wont win every war they play . Zverev is such of enigma of a player , has such a high level game that can beat anybody but he is too inconsistent and mentally all over the place , but because he has the game to win slams he will push trough sooner or later , he is too good not to .
Tsitsipas is the one i have the least faith in , the slam he plays best is the FO yet he has Novak and Rafa there , I can maybe see him beat Novak there but not Rafa , Nadal will bully him on the bh side like he did Roger on clay his whole career .
Thiem could come back , i don't think he is done at all , and he won a slam already , i think he can genuinely beat both Novak and Rafa at the FO but only if he plays on a really high level so it depends can he come back and play like he use to , time will only tell .
Nadal is still a threat at slams , FO he is still the fav , but Novak beat him this year witch shows Nadal is not invincible , Nadal is not winning the AO , conditions are awful for him . He has a chance at WIMB but only if he avoids Novak , i don't like his chances against Novak there . USO , he could win it but has to get a very good draw , he is not beating the likes of Zverev/Medvedev/Djokovic back to back to back , lets just be real here . Biggest issue with Nadal is not so much his game but it's his physical endurance , the longer the match goes the more he gasses out , if he goes to wars back to back i don't see him winning both times .
Federer is just done . The man is 40 , had so many injuries in the last 2 years . He barely plays tennis , if he doesn't commit to the tour and plays like it's his side job he won't win a Masters let alone a Slam . The only slam i could maybe see him having a chance is Wimbledon , but he has to not play Novak there because we know he can't beat Novak at slam anymore , i wouldn't fancy his chances against a few top players even there , if Roger shows the desire to play most of the tour and goes to Wimbledon with enough match play , it is possible he could make a deep run , but to win it ? He needs to get lucky , get an easy draw and pray somebody beats Novak for him , because if he couldn't do it in 2019 he wont do it now for sure .
