Novak Djokovic has claimed that he is currently at the peak of his tennis powers and is just as focused as last year.

The Serb won the Sony Ericsson Open on Sunday and admits that the competition in 2012 is far greater than that of previous years.

Djokovic said: "I feel that being No. 1 and having the best year of my career in 2011, I'm playing at the peak of my form and I'm playing the best tennis that I have played.

"So I have to use that as much as I can, coming into every tournament that I play. The competition is getting stronger, I believe. Everybody is so professional nowadays.

"You have the top players playing in all the top events. That wasn't the case maybe five, 10 years ago. So that makes it even tougher for anybody to win a title. But I'm ready for it."

The 24-year-old has been world number one since July 2011.
