"I am the defending champion in Denmark. It will be tough but I am ready for the challenge of defending the title," Saina told PTI.
"I have been in good form in the IBL. I will give my 100 per cent and I hope to do well in Denmark," added the fourth seeded Indian, who will open her campaign against Bulgaria's Stefani Stoeva, ranked 58 in World, on Wednesday.
She skipped a few tournaments after that to shake off the tiredness and has now regained her strength to compete with the best.
"After the IBL I was tired but I had a good break and I trained hard for the last one and half months and I am fit now," Saina said.
The 23-year-old has not been in the best of form this season and also had some injury concerns and it reflected in her performance as she could only manage quarterfinals and semifinals. So, if she can defend the crown here, it would be her first title of the year.
Another Indian in women's singles, World Championships bronze medallist P V Sindhu will face a difficult opponent in World No. 17 Eriko Hirose of Japan in the first round.
If the world number 10 Indian can get past her, Sindhu is likely to face World No. 2 and World Champion Intanon Ratchanok of Thailand in the quarterfinals.
