Jersey's Elizabeth Cann says she is ready to prove herself at the English National Badminton Championships.
The 31-year-old is the only player in the draw who has won the title before.
The four-time champion told BBC Jersey: "I still want to be number one in the country, and winning the nationals is one sure way to prove it."
Top seed Cann has a bye in the first round, and will meet either Steffi Clark from Yorkshire or Hertfordshire's Helena Lewczynska.
Despite her three previous victories in the women's singles, Cann lost out in the final last year, going down 27-25 in the final game to Jill Pittard.
"It still means a lot to me to win it. I was very disappointed not to win it last year," said Cann.
A commonwealth medal is Delhi is her other major aim for this year, after coming so close four years ago, narrowly losing the play-off for bronze.
Cann said: "I am so determined to get a medal this time. There are a lot of good players around, many of them will have improved from last time, so I have to be as focused as possible and train as hard as I can between now and then."
Cann is also looking ahead to the London Olympics in 2012.
She added: "It's definitely a main aim of mine. I hope to be representing Great Britain there."
The English National Championships start in Manchester on Friday, 5 February.
