Michael Chang is confident men's tennis is in good hands with Carlos Alcaraz and Jannik Sinner, after confirmation of Rafael Nadal's retirement.

Nadal will feature at the Davis Cup Finals for Spain before ending his glittering career next month, becoming the latest of the "Big Four" to walk away from the court. 

Roger Federer called time on his career in 2022, while Andy Murray retired after the Paris Olympics earlier this year. 

While Novak Djokovic – who is one win away from claiming a 100th Tour-level title – remains the last active player from that iconic quartet, Chang is delighted with the next generation.

"I think it's pretty clear at this point, if you look at the matches of both Alcaraz and Sinner, their games are dominating," 1989 French Open winner Chang told Stats Perform. 

"Novak is still playing great tennis and to be able to win the Olympic Games is huge. You know he will still continue to fight for grand slam titles, but the games of these younger players and their confidence on court suggest they will be around for a while, barring any injuries.

"Jannik and Carlos have learned from the previous generation, they learned what it takes to go out and play unbelievable tennis.

"Carlos talks about how he watched these players growing up, how he has learned from them and taken their best qualities to improve his own game, which is very evident.

"They've inspired the younger generation and are well-liked off the court as well.

"Fans can relate to them, they're very humble in nature yet competitive on the court, which is a continuation of that kind of atmosphere and attitude that is really wonderful for our sport of tennis."

Sinner's triumph at the Shanghai Masters on Sunday saw him claim his place at the top of the ATP year-end world rankings, with only Djokovic and Nadal doing so quicker in a season since the modification of those rankings in 2009.

The Italian has won 65 of his 71 Tour-level matches this year, claiming seven trophies, including the Australian Open and US Open.

Alcaraz, meanwhile, won the other two grand slams. 

The Spaniard has won all three of his meetings with Sinner this season, and Chang believes this is only the start of a blossoming rivalry that will go beyond the sport as a whole.

"I think they've already begun to do that. Carlos, in particular, is involved in many non-tennis-related activities and I think that will be pretty commonplace for them," Chang said.

"They're young and vibrant, with interests outside tennis, which is great to see.

"I don't think they'll get side-tracked like some players who have done really well in tennis, and then all of a sudden have this modelling contract over here or this and that over there and then all of a sudden, where did their tennis go?

"I don't see that happening with Alcaraz and Sinner. They seem disciplined, focused, and one-track-minded, but they won't shy away from being involved in other pursuits.

"I think they will keep that focus and will be good for our sport."
