I don't know if you wanted to translate the rest of his "Palabras", psicho, I can only post for Mae a summary of what I've understood, but I'm not sure I got everything right, feel free to correct me!
He first says that now, more than RG, he'd like to win Wimbledon.
His goal for next year is to be in the top 5, it will be difficult to fight for the #1 spot if Federer and Nadal continue like this, but he'll try to put them under pressure.
The Carla part with the usual declaration of love, nothing really new here.
He says he's controlled 20 times a year and doesn't take anything. Even when he had the flu at the US Open, he first played 3 days without taking any medication. He feels insecure because of this. The ATP/ITF should inform them better and do something. It's too hard to play in these conditions, especially during the Grand Slams, with only one day to rest between 5-set-matches.
You already know what he says about Puerta.
2005 was a good year for him. A lot of people say he only won a small tournament in Umag, but he thinks he had very constant results in GS. He clearly wasn't playing at the same level as in 2003 and 2004 when he was in the top 5, but after his surgery, his goal was to be 15th-20th in the world and even that seemed very difficult. So he's satisfied with what he's achieved.
He'd like to be a young father, and certainly not like Agassi who continues playing with his children watching him in the gallery. He doesn't know if he's going to retire at 26 or 30 (I hope I got this part wrong!
), he just wants to be a young father (like his own mother, she is 41 now). But he's not ready yet.
In the first part, they also say he's leaving to Australia on the 6th January.
His physical trainer explains they worked on a lot of things last year and wonders if that could be a cause for all the df. There are many factors in his opinion, the shoulder was one factor (you need 15 months to "stabilize" everything after such a surgery). But maybe he also needs psychological help on this point and if it's necessary, they'll add a specialist to the team.
