Former world number one Justine Henin believes Naomi Osaka has now established herself as the 'boss' of women's tennis.
The Japanese star was in exceptional form as she dismissed Serena Williams in the semi-finals of the Australian Open on Thursday to power into her fourth Grand Slam final.
And, after watching Osaka boss a great like Williams, Henin thinks it is clear there has been a passing of the torch.
"To me, women’s tennis has a new boss," Eurosport expert Henin said.
"Naomi Osaka has this capacity, she has taken another dimension. I think she is charismatic, she doesn’t have a lot weakness, she does have her ups and downs.
"She can improve on the percentage of first serves. She sometimes does a lot of mistakes but I was also impressed when she has to play well, when she has to serve well, she plays like a champion.
"I’m very confident she will win more Grand Slams."
Osaka will be the heavily fancied to win a fourth Grand Slam title in the final against Jennifer Brady, and Henin is struggling to see her not winning it.
"Clearly Osaka will be the favourite in the final, it wouldn’t be honest to say the opposite.
"You always have to be careful – Brady was really nervous today because it was a huge opportunity, it’s going to be completely different I think in the final.
"Naomi Osaka is completely ready, physically, mentally she showed that she is really strong. Naomi, for sure, will be the big favourite for this match."
