Q&A: Juan Carlos Ferrero JC answers your questions from the BBC.
Are you physically 100% - if so, how difficult is it to regain top form?
John, UKPhysically I am 100% since December of last year. I was working very hard before the Davis Cup final to prepare and I've felt 100% from then until now. I haven't had any injuries from then until now. My game? It's always difficult to be 100% but I'm in a good way at the moment because I feel 100% again mentally.
What are the differences when entering tournaments as a lower-ranked player, as opposed to being a top seed?
Estella in IrelandBecause I'm no longer seeded it's tougher ¿ I had to play against Joachim Johansson in the first round last week in Marseille. In the past when I was a top seed I would have played a match like that in the quarters or semifinals. This is the big difference but I have to do it to get higher in the rankings.
Do you think you can get back to your very best in time for the French Open?
Sebastien, FranceI don't know when it is going to happen, but I have a lot of confidence in me that I will be the same Juan Carlos as I was before, and very soon.
You had back and rib injuries last year as well as chicken pox - what was the lowest point of 2004?
Carlos, SpainThe difficult moments were when I knew that I had the chicken pox and that it would take two or three months to recover. I had to start from zero again physically because the virus left me at zero per cent. When I started to come back I had my rib broken when I fell on court and that was another two months out. Those five months were pretty difficult for me.
How surprised were you to be dropped for the Davis Cup final?
Jose, SpainIt was difficult because I had been playing well for the whole year and the coaches told me that I would play, but then I had some problems with my hand two days before the Friday matches so they decided to choose Nadal instead. It was difficult for me not to be in the Friday matches but I had to understand. Inside me I wanted to play but this was the decision of the captain and they had to make it.
Do you plan to play for the Spanish Davis Cup team this year and do you think that Spain can retain the title?
Vinka, CroatiaIt's always very difficult to retain the Davis Cup title and this year we would have to play two or three rounds outside Spain. This makes it very difficult because the other teams will put down very fast court surfaces down, but maybe we can. You never know!
You've been number one and won a Grand Slam title. What goals do you feel you haven't achieved yet?
Izabella Vermesi, RomaniaI want to enjoy tennis, feel the enjoyment of the people as they watch my game and I want to get some titles ¿ some Grand Slams and some Masters Series, and to try to get my ranking very high again.
You have had a great career already but what's been the highlight so far?
Paul, Solihull, UKWinning the Davis Cup, the Grand Slam title in Paris and becoming the World Number One. Of course playing in the end of year Masters three times was good as well. Just saying it sounds good!
Who has the hardest serve to break?
Rodney, ParisThere is more than one - probably Joachim Johansson, Andy Roddick and Wayne Arthurs. All of these guys are very difficult to break.
Besides the other Spanish players on the tour, who are the players that you get along with the best?
Caitlin, USASouth American players of course, but I have good relations with everyone. The language with the South American players helps a lot but I also get on well with the other European players. The American players stay together and so we don't talk a lot, but I still have good relations with them.
Describe yourself in three words.
Jo, EnglandThis is difficult! Simple, normal and a family-guy.
What is it like to play against Andre Agassi? What are the secrets to beating him?
Mark Witchell, United KingdomI enjoy playing against Agassi. The secret is not to make many mistakes because he makes you run a lot on the court and you have to be confident. When I played him I was really playing well and I need to be because he can play to such a high level.
In terms of sheer talent, who do you think is a better player: Roger Federer or Pete Sampras?
Rishi, HollandI prefer Sampras. He does everything so easily in the court. Roger does too, but I prefer to watch Sampras.
Do you enjoy playing in England and is it conceivable that we might see a Spanish men's Wimbledon finalist soon?
Oliver Hughes, United KingdomI enjoy to play on grass courts and I've played good matches in Davis Cup on it as well as reaching the fourth round twice at Wimbledon. Maybe Some year I can do even better at Wimbledon but it's difficult because we don't have any grass courts in Spain to practice on. We can only play on synthetic grass courts which are a little bit different. Maybe one day one of us can win at Wimbledon.
What will you do when you aren't a tennis player any more?
Corinna, GermanyGood question! I would like to be a soccer player or a motor racing driver.
Do you see Rafael Nadal as a future World number one and if so, when?
Alex, SwitzerlandHe's very young but he does everything well. If he continues like he is he will be in the top ten for sure. I don't know if he can be the World Number One but I think he can definitely make the top ten.
