Like Muhammad Ali versus Joe Frazier, the two best heavyweights of tennis clash on the sport's most hallowed grounds when Rafael Nadal faces new number one player in the world Novak Djokovic in the Wimbledon Final.

This will be one to remember, as both Nadal and Djokovic have been exceptional. It's somewhat rare that two players who are on top of their game and in the prime of their careers can meet in such a high-stakes match.

Who goes into Sunday's match the favorite?

Djokovic has had a fantastic tournament, though he made the Final without beating Roger Federer. The 24-year-old Serbian is in his first Wimbledon Final, and he will be hungry to win a Grand Slam other than the Australian.

Djokovic matches up well with Nadal considering Nadal doesn't have an overpowering serve, and Djokovic has an excellent return of serve.

Always is tough -- really difficult to play against Novak, said Nadal. He's playing fantastic this year already. He only lost one match during all the season and I lost already four times this year against him.

But Nadal will go into the Final the favorite. He has been in three-straight four-set matches, but Nadal's ground game is just too good. The Spaniard is an amazing combination of athleticism and focus.

The defending champion has proven to be great on grass, and will likely step up in the Final. He beat a tougher challenger in the Semi-finals by dismantling fan-favorite Andy Murray, and continues to ride high after winning the French Open by beating Federer.

PREDICTION:

Nadal in straight sets, but each set will be a nail-biter.
