For Tommy Robredo, Rafael Nadal has always been the toughest player to play against however the Spaniard can't say who the GOAT is right now.
The GOAT debate will never end in tennis simply because it's so hard to choose between three legendary players who all have a very strong case. In a recent interview, Tommy Robredo reflected on the big three admitting that for him, Nadal was the toughest to play:
"Rafa [was the toughest to play against], for the way he plays, with this speed of the ball, the spin of his forehand, for the difference due to him being left-handed and for the way that he runs after every ball as if it was the first. I don’t say the others are easy.. but for me Rafa had something that makes you suffer more inside the court than the rest."
Robredo then talkeda bout the GOAT race, admitting to Sporskeeda:
“Right now, I would say it’s close between Rafa and Novak. It depends if we say Grand Slams are the most important or also consider how important Davis Cup, weeks at No 1, and other factors are. It’s very difficult to say at the moment.”
