Roger Federer believes it would be "phenomenal" if Rafael Nadal prolonged his career into 2025 but admits it is up to the Spaniard himself to make that choice.
Nadal last played at the Paris Olympics, where he competed in both singles and doubles, and has since ruled himself out of the US Open and Laver Cup.
It is still uncertain whether the 22-time grand slam champion will continue to play next season, but his long-time rival Federer would love for him to play on for just a bit longer.
When asked how he felt about Nadal pulling out of the Laver Cup, Federer told dta: "I really hoped he would somehow get a match in the end, but he just said he'd rather not do it, and that he doesn't feel ready.
"But he seems good. I think he just has to decide what to do next, and I think that's what he's going through at the moment. He's done everything for the sport.
"It would be phenomenal if he could go on for another season, but only Rafa himself can answer that. In the end, it might be helpful to make a decision at some point."
Furthermore, the eight-time Wimbledon champion still believes Novak Djokovic is one of the favourites for next year's Australian Open, despite the Serb not picking up a Grand Slam title this season for the first time since 2017.
He said: "Novak, winning the Olympics and playing somewhat, let's say a full season - he didn't bow out because of injuries, he chose to play less, which is normal when you get a bit older.
"I feel like he has chances moving forward. I look forward to Australia, which is the next Slam. I think [Novak is] definitely going to be one of the favourites along with [Jannik] Sinner and [Carlos] Alcaraz."
Djokovic is a 10-time champion in Melbourne but fell to defeat against Jannik Sinner in this year's semi-finals.
His next event will be at the Shanghai Masters, which commences on October 2.
