According to Serena Williams’ former tennis instructor, Rafael Nadal’s unique qualities are what set him apart from the rest.

Rick Macci, Rafael Nadal’s coach, has said that the Spaniard’s record on clay is “absolutely astonishing,” and that Nadal is “almost bulletproof” when it comes to dealing with pressure. Nadal, at age 36, set a new record by defeating Casper Ruud in the final of the French Open to win his record-tying 14th title.

Nadal has won 22 Grand Slam titles, an unprecedented feat. Nadal has had an injury-plagued year, but he still won two Grand Slams and advanced to the semifinals of Wimbledon before withdrawing due to an abdominal injury.

Tennis-Infinity asked Macci, who coached Serena and Venus Williams as kids, how long he thinks the Spaniard will play given his ongoing battle with foot pain due to Mueller-Weiss syndrome.

Nadal is a machine, according to Macci.

“Nobody knows what’s going on in his head or with his health.

It’s unheard of to have such a high winning percentage on that court. What he has accomplished is unprecedented, even in tennis, when you consider his track record. His physical agility may have diminished by a quarter of a step, but his fighting spirit remains undimmed, and his ability to deal with stress is remarkable “As Macci revealed to Tennis-Infinity,.

“If he stays in good health, he can play for as long as he likes, but he’s hardly a role model. Like Federer, he shows young players how to respond positively to defeat. He’s so efficient it’s scary. You can’t just wake up one day and be that way.

Since he was a young child, he’s always been like that.” Nadal returned to Spain after being forced to pull out of the Wimbledon semifinal. On Monday, Nadal was back at it on the practice court, getting ready for the Montreal Masters, which begins on August 7.

Nadal was upset to miss the Wimbledon semifinals, but he ultimately decided to withdraw because he didn’t want to risk being sidelined for several months.
