Naomi Osaka could get to double figures in Grand Slam titles, says Mats Wilander after watching her win number four in Australia.
The Japanese star had too much power for a spirited Jennifer Brady on Saturday, and she now preserves her perfect record in Grand Slam finals.
And, speaking in the Eurosport cube after the match, Wilander says there are likely to be many more major titles to come.
"I think she has 10 [Grand Slam titles] in her, minimum, I really do," Wilander said.
"Of course we know that motivation is important. Physically she doesn’t move really well, she’s so strong and she doesn’t look like she can get hurt very easily.
"She is very subdued when she wins which means she wants to win more. I think everything is pointing towards winning at least 10 majors."
Serena Williams has set the bar incredibly high for women in the modern era, just as Steffi Graf set the bar high for Williams, and Wilander thinks Osaka has some way to go in terms of development before she can challenge the American's legacy.
"It’s hard to say, but if she can learn to volley a little bit then that’s a possibility, if she can learn how to hit a sliced backhand then it’s a possibility.
"We know when you are winning you don’t necessarily want to switch up your game too much but there will be a day when she loses a bit of confidence, and when you lose a bit of confidence how far down the ranking do you fall, for how many months or a year.
"If you have a ‘B’ game then maybe that fall is not as severe, maybe you only go away for a few tournaments.
"I think that’s where she needs to improve, but when you are playing as well as this, there is no reason to improve anything else."
