"I'm so happy today because I haven't been able to beat him before. It was a really important match for me," Ginting told Olympics.com after.

"I played with nothing to lose, didn't think about our previous meetings. I enjoyed every single point, so finally I can beat him.

"The key was the third set on the crucial points, and I tried to push him as hard as I could."

"I think I did pretty well today. There’s good things I should learn from this but I need to prepare more from the next round," he told our reporter Shintaro Kano.

"Hopefully I’ll do better.It doesn’t mean that if you have a higher ranking you are going to lose. It doesn’t mean if you are more popular you are going to beat me. I think it depends on your performance that day.

"Prannoy definitely did bet a lot of major opponents but I will be more prepared for him.I’m no thinking too far ahead. I’m just thinking about tomorrow’s match. Hopefully I can win tomorrow and then I’ll think about the next match."

The Indian shuttler caused an upset to beat recently-crowned Commonwealth Games champion, and compatriot, Lakshya Sen in their Round-of-16 men's singles match.

"Kento and Lakshya are two good wins back-to-back," he told our reporter.

"It's been a tough draw for me and to beat someone that is in form... it's always great to play him. I played really well and just had to be patient enough to stick to the plan.

"It was all about who executed better on the day, and the mind games come into play as I know him so well, so I had to stay extrememly focussed.

"I had a lack of match practise in the past few weeks, so I was a little bit tentative going into this match, but now my confidence is building.

"Zhao has also had a good few wins including Lee Zii Jia, so he'll be tough to beat tomorrow."

But, showing greater patience and tremendous determination, he bounced back to win the next two games in comprehensive fashion and book his place in tomorrow's quarter-final against Zhao Jun Peng.

"It's always tough [playing against Sen], he's one player that's improved tremendously over the past couple of years. It's always tough to beat players who have a lot of confidence," Prannoy said after.

"His defence is super solid and there are no easy points with him.

"It took its toll on my body and I'm wondering how I will play tomorrow. I'll have to get a good sleep tonight as the last one I lost against him!"

"I had a lot of mistakes and Zhao played a very good game today. He controlled the game, particularly at the net."

"In the second parts of both sets (Thammasin) played really well and made it tough for me. However I’m really I managed to close it in straight games.

Yamaguchi, after beating Takahashi to set up a mouth-watering quarter-final clash vs Marin, "I felt much lighter on my feet than two days ago. She had the lead at one point in the first game but kept my cool and adjusted.

"(Marin) used to have pace and was always an aggressive, attacking player. But since her injury, I don’t know what kind of style she’s adopted. I haven’t played her in a while so I’m looking forward to it.

"The way I match up with her, I have to take the fight to her. If I don’t she will dictate the pace. More than the game plan, I have to have heart against her".

Speaking to Olympics.com after her remarkable come-from-behind win, "I’m really happy to beat this kind of player. This is what I want to be.

"He Bing Jao is a really tough player; she really knows how to play against me. We are both left-handed so we are not use to playing against left-handed players but something I can learn from today is that I need to keep pushing myself, keep going, keep fighting for every point - and this is what I did in the last part of the game.

"I didn’t want to leave this game. I wanted to fight for every point. When I played the first game I was in the far side and sometimes it’s difficult to control the shuttle mainly to the back. But in the second game, I was in the slow side so I could control the shuttle much better.

"This match was really important for me. It gives me some confidence for sure.

"Every game is going to be a test for me. As I said when I came here the first day, I want to go as far as I can. I want to be the best of myself on the court. I just try to be ready again tomorrow".
