Bjorn Borg, who has developed a close relationship with Roger Federer through the Laver Cup, says the Swiss star has five main goals for 2021.
Roger Federer was unable to play in the Australian Open after over a year out with a knee injury.
However, he is set to return in Doha next week, and Borg says he is focused on a few select targets for the season.
“It's a pity that Roger decided not to play in Australia, he had a chance,” Borg told La Stampa.
“But for 2021 he has five goals: the first is to stay fit, the others are Wimbledon, the Olympics, the US Open, and the Laver Cup.
Borg has worked with both Nadal and Federer as part of his role as the Team Europe captain at the Laver Cup, and he says he has grown to admire them both not just as players but people too.
“They're two of the strongest ever, they know what to do,” Borg said.
“I am rather impressed with how motivated and focused they are on the pitch. And they are great people even outside of tennis.
"They know what I did, and I know what they are doing. I'm much older, but I've been through their own experiences, that's why we understand each other perfectly."
“Nadal in Melbourne has won once, but he could have done it two or three more times.
"In Paris he will certainly be the favourite, but let's not forget [Stefanos] Tsitsipas, [Daniil] Medvedev, [Denis] Shapovalov,[Alexander] Zverev who can do well in all the big tournaments.
"And then [Novak] Djokovic: he wants to win as many Slams as possible to overtake Federer and Nadal.”
