Osaka keen to discover 'champion mentality' after Melbourne exit
Naomi Osaka says she needs to develop a "champion mentality" after her Australian Open defence was ended by Coco Gauff.
Osaka became the American teenager's latest victim as she slipped to a 6-3 6-4 defeat in just 67 minutes in the third round at Rod Laver Arena.
The Japanese star could fall out of the top 10 as a result of her defeat in Melbourne depending on the results of others.
Osaka, who won the US Open in 2018 but fell in the fourth round the following year, feels she needs to find a way to win when things aren't necessarily going her way if she is to win majors on a consistent basis.
"I don't have the champion mentality yet. That is someone who can win when they are down," Osaka said.
"Sometimes I get overwhelmed and I don't know what to do in these situations.
"I have an age problem - I don't like losing to people younger than me. So I took this very personally."
