When discussing Djokovic’s future Grand Slam credentials, Del Potro told the Olympics that he backed the 37-year-old to win a 25th major title.
“Winning a Grand Slam is something very personal for him, I believe,” said Del Potro. “I believe he can win more Slams. In tennis terms, he is the best. He has a lot of experience.
“If he can be in good physical shape, he will keep trying and possibly succeed. It would be a great thing for the world of tennis if he manages to win again after some time, as he did in Paris with the gold medal.”

With Del Potro, Federer and Nadal all now retired, the former world number three has revealed what made them so difficult to beat.
“Many of us played well, but they had a difference in details, because it’s not just tennis,” said Del Potro. “It’s mentality, physique, personality, how to deal with pressure.
“For many years they did this better than us, especially in the most important moments. In other tournaments on the circuit, they play at a level eight or nine, and at the Slams, level 10.”
