An elbow injury has meant that Sarah Sjöström has had to fight her way back to swimming.

Since returning, butterfly swimming has been the most difficult.

But a few days ago, the Swedish swimming queen announced that she had become "more curious" about competing in 100 meter butterfly swimming during the Olympics.

Now it is clear that she has decided to stand up.

- I do not expect any world records, but I am curious about how much better I could have been since Rome, she says at a press conference on Thursday according to Sportbladet.

- I'm not in the shape of my life, but I'm realistic.

But I make progress all the time.
