Ever since I did that 57.9 last year, the Americans have been analysing me in detail. You can see on the swimming web pages. They are breaking it down in every detail. How many strokes I take. How quick I am in and out of the wall.

I am stronger than I was last year. I am throwing the ball better now in May of 2013 than I did in May of 2012 - significantly better. I got better throughout the season.

For the last seven years, I have been racing the best in the world and making my way through the ranks. I am in that spot where I have got a real opportunity to produce something. I am not going to take it for granted because I know those guys will step it up.

I'm going into my first Olympics, whereas people I'm racing against are going into their third and fourth and probably last Olympics. So there's more pressure on them to perform. I've still got a whole future ahead of me. I am not even the Olympic champ.

I'd like to see us improving on what we had last year.

Don't forget this club nearly went out of extinction last year.
