SINGAPORE - The women's singles gold medal at this August's Olympic Games is anyone's for the taking, said world No. 1 Carolina Marin.

The two-time world champion is in Singapore this week hoping to gun for her first OUE Singapore Open title.

Said the Spaniard: "There are many good players and all of us want to fight for the medal.

"We will see what happens in the right moment. Maybe it's not me, maybe it's not the Chinese, maybe it's another player. We will see which player (challenges best)."

She named in-form Ratchanok Intanon, the former world champion from Thailand, as one of the ones to watch, not just this week but also in Rio.

While she admitted she also has her sights set on a historic gold for Spain at the Olympics, she is cautious of putting pressure on herself.

"I am the world No. 1 but I don't want to think that I want to win all the tournaments. I want to enjoy every match that I play and show my best badminton," she said.

The Singapore Open is the final Superseries tournament before the Aug 5-21 Olympics in Brazil. Singapore shuttlers such as mixed doubles pair Danny Bawa Chrisnanta and Vanessa Neo are also in the hunt for precious ranking points.

World No. 8 Saina Nehwal of India was the most high-profile withdrawal on the day before the start of the event due to illness. China's world No. 23 Xue Song, India's No. 18 Kashyap Parupalli and 2014 Singapore Open champion Simon Santoso of Indonesia also withdrew on Monday.

Singapore's women's singles players Yeo Jia Min and Chen Jiayuan pulled out due to injury.
