Jannik Sinner is 23 years old, Alcaraz is 21 years old. That's a lot of years to give up when your opponents are at the same level as they are.
But Grand Slam titles have been won regularly by great players in their mid-30s over the past decade, and Edberg has played his part.
The Swede was part of Roger Federer's coaching team in 2014 and 2015, and he is sure Djokovic's fire is still burning.
“These guys have a lot of people around them and they love being there. Especially since Novak is chasing a lot of records, I think that's motivation enough,” he said.
He added: “He is still in very good condition, and this will at least give him a chance, even if it is very difficult this time.”
What is clear when talking to Edberg is how top players now feel no psychological barrier to winning in their 30s. While the length of the season is still difficult, he says smarter scheduling helps.
“If you look at my career, I think what burned me in a lot of ways was participating in the Davis Cup,” he explained.
“We've been to six Davis Cup finals in a row, so that means playing until December and then starting the season again.
“It shortened my career when I look back on it. Physically, I could have played for another five years.
“At the time I was playing, the chance of winning the majors at 30 or 31 was very slim. That has changed now.”
Edberg retired in December 1996 at the age of 30, after another appearance in the Davis Cup Final.
