Former World No.4 Kiefer believes Alcaraz has 'no weaknesses' and is a 'complete player'

Carlos Alcaraz has been viewed as the next dominant force in tennis, and former World No.4 Nicolas Kiefer is of the opinion that the Spaniard is a 'complete player with no weaknesses in his game.'

Kiefer heaped praise on the US Open champion, lauding his offensive and defensive skills. Furthermore, he highlighted Alcaraz's speed, in addition to his occasional serve and volley style of play.

"Carlos Alcaraz is a very, very complete player. In my opinion, he has no weaknesses," Kiefer said. "He is excellent both offensively and defensively, he has incredibly fast legs. In addition, he also varies a lot with his service and volley game."

The retired German also had good things to say about rising stars Jannik Sinner and Holger Rune, stating the trio could dominate the men's circuit in the near future.

"With Rune we are facing a guy who is revolutionizing tennis, he is not afraid of anyone, as we saw in Paris-Bercy," added Kiefer. "With Jannik the situation is a little different, he is a tennis player who bets more on brute force.

"He [Jannik Sinner] started playing at this level of tennis a little later than Alcaraz and Rune did, which also shows that there are many roads and times to reach the top."
