The world no.2 stresses #Nadal is his ultimate opponent, having met in some brutal battle through the years.
#Federer has reached 29 #GrandSlam finals to Nadal’s 23 and has three more victories than the #Spaniard.
But Federer says without Nadal he couldn’t have won so many.
“We shared many strong moments on court and off court in a very friendly way. As soon as we grew up, I realised how much Rafa was important in my career,” he told #Tennis World.
