According to former Wimbledon champion, Mario Bartoli, Rafael Nadal no longer has what it takes to be in the big four. She thinks that considering the form the Spaniard has been all year and early exits from the second round at Wimbledon proves that Nadal at the moment is not capable of competing with the top players.
"When you play against him [Nadal] the ball is 25 kilometres per hour slower, the opponent doesn't have the same difficulty to play," Bartoli said. "When he serves, he can't go beyond 115 miles per hour.
He is exposed in every return.” "There is an [solution] and his team need to find it because it's vital for him." However, Bartoli later on in the interview did reveal that she is also one of the believers in Nadal making a comeback to the top level.
As she thinks, the group of 6 players at the top are in a league of their own. "There is a group of five or six players [at the top]," Bartoli said. "There is Novak [Djokovic], Andy [Murray], Rafa, [Kei] Nishikori, [Tomas] Berdych [and] Stan [Wawrinka].
This group is at the top, top level. "The level and the difference between the players is very small." ALSO READ Boris Becker says Roger Federer is the GOAT
