Nadal: I’ll need to be at my best to beat Dimitrov

Rafael Nadal has hailed the "unbelievable talent" of Grigor Dimitrov and he knows he will have to be at his best to defeat him in their Australian Open semi-final on Friday.

The winner of the match between the pair will face Roger Federer in the final after the Swiss overcame his compatriot Stan Wawrinka on Thursday.

Nadal has an impressive 7-1 head-to-head lead on the Bulgarian but that won't ease his worries over facing such a fearsome opponent.

"He's a player that has an unbelievable talent, unbelievable potential," Nadal said. "He started the season playing unbelievable.

"It's going to be a very tough match for me. I hope for him, too. I'm going to try to play my best because I know he's playing with high confidence.&quot

Alexander Zverev, Gael Monfils and Milos Raonic were all defeated on the Spaniard's way to the semi-final and Nadal is pleased with his own form in the lead up to the clash.

"I think all of them are top players. So that's very important for me because that means that I'm competitive and playing well," said Nadal. "Very happy that after a lot of work, to be in this round again. Is a special thing for me, especially here in Australia.&quot
