Roger Federer Admits Rafael Nadal The "Most Intense" Rival

"The most intense rivalry I have ever had was with Rafa, no doubt on that. It has been an epic and incredible rivalry and it will continue to be like this because we are going to play often in the future," said the 34-year-old Federer in an interview to Tennis World.

The duo met in Grand Slam finals eight times before and almost every time the 29-year-old Spaniard outsmarted Federer. Nadal won Federer 5-0 at the French Open (2005 to 2007, 2008 and 2011), 3-0 at the Australian Open (2009, 2012 and 2014) and 1-2 at the Wimbledon Championships (2006 to 2008). However when the titles won by the two formidable players are tallied the Swiss has the upper hand over the Spaniard.

"He made me change my game many times since he is lefty and we had never seen a player who could hit the ball with so much spin. If we see the way I played in 1999 and the way I play now, the change is brutal. Now I play with more strength, before I had such a 'soft' game. My movements, the way I hit the ball, I'm a different player due to Rafa's presence," said Federer.
