Maria Sharapova won five Grand Slam titles in her career, and for a time, she was even considered a great rival of the female tennis greatest of all time Serena Williams.

That should entitle her to get some props as one of tennis' best.

However, her former agent Max Eisenbud does not see it that way. For him, the Russian star is the worst athlete ever to win a Grand Slam.

That's not a dig on his former player, though. Max only thinks she is the worst because of her different skill sets compared to other players.

"I mean, I tell people all the time she's probably the worst athlete that, and I'll tell her if she was here (laughing), the worst athlete to ever win a Grand Slam," Eisenbud said during an appearance at The Tennis Podcast.

"She can't throw, she can't pass, she has no touch but she willed her way."

The agent added that difference is what Sharapova used to climb her way to the top.

"I think she was the most mentally strong players to ever play the game and I would put her on that list with all that great champions."

Moving on with a new project

Sharapova has long retired, and Eisenbud has a new client in 20-year-old Emma Raducanu.

The agent can't help but marvel at what the British smasher did in the 2021 US Open.

Then 18 years old Raducanu won the US Open to become the first qualifier to win the tournament. Not only that, she did it without dropping a set the entire tournament.

"That was incredible. What she did will never happen again," he said in the same podcast.
