I know this is an utopic idea but if it would be like this according to me Federer would be beaten in 3 sets in Wimbledon final. I imagine Federer's helpless look at Rafa in the final if he would have Ivanisevic's huge lefty serve. All of Federer's beliefs of defeating Rafa on any surface would have gone in that match after such a defeat on grass especially in Wimbledon final))
What do you think of such a dream final?
Nadal would beat him at worst 6-4, 6-4, 6-4.
Without the serve Nadal will beat him 7-6(12),2-6,7-5,5-7,10-8
What if Federer had Nadal's balls?
He would be the GOAT and a multiple RG champ.
He would play Spartan tennis.
Also, he would be a guy and dump Mirka and find someone hot.
