Rafael Nadal Can Break Federer's Grand Slam Record: Goran Ivanisevic

Goran Ivanisevic, who won the Wimbledon in 2001, has called Rafael Nadal a 'fighter' and has backed him to win more Grand Slams. The Roger Federer-Nadal rivalry is seen by many as the best tennis has ever seen with the two players having won 31 Grand Slam titles between them (Federer 17 and Nadal 14). Ivanisevic is the only player ever in the history of Wimbledon to have won the championship with a wildcard.
