A Nadal v Federer final is a mouth-watering prospect for many and will be the case should the Spaniard account for Bulgarian No.15 seed Grigor Dimitrov on Friday night.

But despite having the upper hand in past match-ups, “Uncle” Toni is under no illusions at how difficult it would be to stop the 17-time grand slam champion from collecting another major.

"When we're in a final, normally I'd prefer to be against a bad player," Uncle Toni said.

"I like to watch Federer playing but I don't want too much to be playing against him in the final.

"People say it's a dream final, but I say that it might be for them but when I dream, I dream about Rafael meeting the worst player in the tournament."

Uncle Toni said he understood the public’s desire to watch the two legends of the court face off in an epic final on Sunday.

"The possibility of playing Federer in a final could be good for tennis and it could be good for us too," he said.

"I have very good memories of the matches that we've had against Roger. But I know that when you arrive in a final against Federer it is very difficult."
