London, Mar.12 : Swedish tennis great Bjorn Borg believes that Spanish tennis star Rafael Nadal has the potential to end Roger Federer's run of five straight Wimbledon titles.

A five-time Wimbledon winner himself, The Sun quoted Borg as saying: "Nadal can play on any surface. If I were to pick the champion I'd pick Nadal.

"He knows he can win on grass now. He's a great player."

The Federer Nadal contest is definitely one of the most interesting in tennis today.

Nadal is ranked World No. 2, is a three-time French Open singles titlist (2005-07), and a two-time singles runner-up at Wimbledon (2006-07).

Nadal is undefeated at the French Open, having won all 21 matches played at that tournament. Nadal is well known for defeating current World No. 1 and 12-time Grand Slam singles titlist Roger Federer at the French Open in 2005, 2006, and 2007, so far denying Federer a career Grand Slam.

From April 2005 to May 2007, Nadal won a record 81 consecutive clay court matches before being defeated by Federer in the 2007 Hamburg Masters final.

This is the longest winning streak among male players on a single surface in the open era.

Federer has been ranked World No. 1 since February 2, 2004, for a record 215 consecutive weeks. He is widely regarded as the best player of his generation and among the elite group of all-time great male tennis players.

In 2008, he was named Laureus World Sportsman of the Year for a record fourth consecutive time.

Federer has won twelve Grand Slam singles titles (three Australian Open, five Wimbledon, four US Open), four Tennis Masters Cup titles, and fourteen ATP Masters Series titles.

He appeared in a record ten consecutive Grand Slam men's singles finals (2005 Wimbledon Championships through to 2007 U.S. Open), before this streak ended at the 2008 Australian Open.
