ZHUHAI, China - Former World No.1 Garbiñe Muguruza will finish 2018 outside the Top 10, but she is not too disappointed with her year overall, which has been marred by injury.

"I knew at some point that some ups and downs were going to come, especially with the body, or just it's very difficult to keep for a lot of years the same high level - it's kind of tricky for everybody," she told reporters prior to the start of the Hengqin Life WTA Elite Trophy Zhuhai.

"I'm just trying to keep the enthusiasm. I feel I'm a very competitive person, so even though there is tough moments or you feel injured sometimes, I know that the hard work will pay eventually.

"So I'm just going through and trying to improve so I can be better in the next season."

The 25-year-old is a two-time Grand Slam champion - and this year at the majors she reached the semifinal of the French Open, a tournament she won in 2016. 

However, she did not make it past the Round of 64 at any of the other three Slams, despite being seeded at all of them: at the US Open, she lost to Karolina Muchova 3-6, 6-4, 6-4, at Wimbledon she lost to Alison van Uytvanck 5-7, 6-2, 6-1, and at the Australian Open she lost to Hsieh Su-Wei 7-6, 6-4.

The Spaniard will compete in Zhuhai for the first time, and says she is happy to be there - as well as happy to be at the end of a long season.

"It's also exciting because I've never been here in Zhuhai - it's a different format," she added.

"Yeah, I think there's plenty of reasons to be happy to be playing here and hopefully get a good win and finish the year with a good taste."
