That is the belief of Roger Federer’s close friend and former Davis Cup team-mate Yves Allegro.
Nadal is currently training for the clay at his academy in Mallorca, weeks after being forced to withdraw from Indian Wells with a knee injury.
The Spaniard was due to face Federer in the semi-finals but a knee problem meant he took the decision to pull out.
The 11-time French Open champion expressed confidence that he would be ready for the clay season.
And he has looked in good shape in the footage shared on social media.
Nadal is expected to play at the Monte-Carlo Masters, which begin on April 14.
Djokovic, who lives in the French principality, is also due to play and it could lead to this season’s first match-up between them on the clay.
Djokovic and Nadal will be going head-to-head for honours on the clay with history at stake for both.
But Allegro has given the edge to Nadal over Djokovic and Federer.
“As long as Nadal plays tennis, he will remain the big favourite whenever he steps on a clay court,” Allegro told Swiss outlet Bluewin.
“However, Nadal has been able to beat Djokovic regularly on clay.
“It’s a kind of vicious circle: Nadal’s game is perfect to annoy Roger, Djokovic’s game is ideal to annoy Rafa, and Federer’s tennis is perfect to annoy Djokovic. That’s why the trio has always been so interesting.”
Federer will play on the clay for the first time since 2016 and when asked if the Swiss star was still capable of competing against the best on clay, Allegro said: “In this regard, I see no problems.
“For me, he is the favourite against every player, except for Nadal and Djokovic.
“I’ve always said that sand is practically Federer’s best surface.
“In the last 15 years he was clearly the second best player in the world on clay.”
