SOUNDBITE: (Spanish) Rafa Nadal, tennis player:

"Novak Djokovic was a very good player back in 2011, 2012, 2013 and he also is in 2015. We all have times when we win more and periods when we win less. You can't win everything all the time. Djokovic had an impeccable year during 2011. And he is also experiencing a perfect season this year. We have to congratulate him and accept that today he is the best player in the world. Proof of that is all he has won so far this year. As for me, I have to work hard so I can play to my best and rediscover the very high level required to put up a fight against him."

SOUNDBITE: (Spanish) Rafa Nadal, tennis player:

"I felt good in Monte Carlo. I am confident I will be back to my normal, calm state of mind. As for winning or losing, there is always a rival in front of you who also wants to win. The matches I've been drawn in at the Barcelona Open look very difficult from the beginning so I don't know what will happen. If you ask me how I feel I will tell you I feel good. I feel physically strong and confident that I'll have a good tournament here. From a tennis standpoint I feel much better today than a few days ago with regards to physical shape and state of mind."
