I had found that interview a few days ago and was working on the translation. Since it's so long I'm just going to make a general translation

hope you don't mind.
They start talking about how much winter sports have grown in Valdemoro (which is where they are, at the south of Madrid), particularly figure skating, with the goverment recently taking interest in its development.
I think the interviewer knew next to nothing about figure skating since he asked Javi if there was a chance that the girls behind them (who btw I think they were totally crushing on Javi when they were not training) could fall and slide all the way to where they were. Javi said that it was not likely since they were not going very fast, and the guy asked if one should brake diving the blade against the ice and Javier said no because you can have a nasty fall.
He then asked Javi if he was at that rink with humble intentions or thinking he's the World Champion and kind of like showing off. He said that of course he wasn't and that he's received lots of presents and was very willing to take pictures with the kids. And the guy kept insisting if he has not acted like that at all since he won. Javi said that he sometimes did it with his friends and colleagues but in a good-natured way.
The interviewer asked about how he handled his rivals, the Russian, the Slovakian (?), if they were now more careful about him as a rival. Javi said they've known for some years now that he is a rival to deal with, but that they've noticed that he's now in the position to be chased, so to say. That they will now compete to stop him from winning another Title, specially Yuzuru who is his strongest rival (the guy had no idea who he was). Javier started talking about how Yuzuru is the top skater and that they trained together, he then said that he spends the majority of the year in Toronto and visits Spain once or twice per year.
The interviewer was really surprised about the fact that Javier and Yuzuru train under the same coach and at the same time, he said it's something you don't see in other sports, champions training side by side. Javier then explained that, for the first time in history, a coach (Brian) had their 3 skaters placing 1st, 2nd and 5th. That he has a great team and the results are more than visible. He asked if working alongside Yuzuru favored him or kind of angered him that his main rival knew him so well. Javi said it favors them, seeing someone training at your own level pushes you if you're having a bad day. Though he said he sometimes gets a little upset when Yuzuru is having a really good day and he's falling all over the place but he doesn't show it, so he comes back the next day with the idea of doing it better. The guy asked him what is Yuzuru's signature move and Javi said that it's kind of everything since he is a very complete and consistent skater and that's why he's such a brilliant skater and the Olympic Champion. But that regardless of how consistent anyone is, there is always going to be a time where you make mistakes and this time Yuzuru made more mistakes than him. The interviewer asked him if Yuzuru was second and Javi got confused and said third but quickly corrected himself.
The start talking about how this victory will push figure skating forward in Spain, that hopefully more people will try to skate and more rinks are made. They talked about how, before, the federations and people working at the rinks were struggling with the lack of skaters (the interviewer joked about them using the blades to cut ham), but Javi said that the main problem was the lack of rinks.
They talked about the local skating organizations and joked about how Barcelona's skating organization is called Football Club Barcelona, but that there's still alot to do since many big cities still lack skating rinks or are very small ('a freezer' they said)He was asked about a day in his life in Toronto and in Spain. The interviewer assumed that anything in Toronto should be much cooler than in Spain and Javi told him to go and stay there for a long period of time and then he'll see how it really is. Javier said he misses Spain a lot and he has a very good time when he visits. He doesn't hate Toronto but it's not his country and the winter is very long (5-6 months).
He says he trains everyday when he's in Toronto, he wakes up and is not a breakfast person but he drinks a lot of coffee. He plays videogames for a while (Call of Duty, FIFA), he says the videogames help him wake up to be ready for training. At midday, he goes to the rink (it's not easy to go earlier), and leaves at around 4. He said he does some cardio but it's all on the ice, with a heart rate monitor and racing across the rink. The guy then asked if it's possible for a figure skater to compete against a speed skater and Javi said that it's not since the training and the skates are different. But he said his marks when he races are not bad, but that he doesn't know what is good or bad, it's just what his coach tells him. He was asked if figure skating was better than speed skating and he said they're different and each has its own difficult stuff. He asked Javi in which sport he's really bad at, and he said that he surely must be bad at golf, since he's already bad at mini golf.
They go back to the subject of his daily life in Toronto and he said that after he finished training he goes home, that he's life is quite boring when he's over there, that his social life is in Spain and that's when he goes everywhere, he sometimes goes out to have a drink with his friends.
The interviewer asked if he was staying until the new season began, but Javier said he would go to Japan for some exhibitions. He said he sometimes has to turn some of these events down since his schedule doesn't allow him to go or the pay is to little compared to all the travelling and preparing.
He was asked about the moment in which he stopped being just another kid with skates and someone saw he had the potential to become a great athlete. He answered it was when he was 16 y/o, when Morozov saw him at a skating camp and invited him to train in the US. But that Morozov told Javier that if he wanted to train with him, he had to be in New Jersey in 10 days and he said yes without even telling his parents beforehand.
The interviewer then started asking about figure skating in general if it was divided in skating, spins and jumps. Javier said there were also steps and transitions which were all very specific that they needed to get the levels. And that on top of everything, you must smile and pretend you're not tired even though they're dead, or the judges might take notice.
They asked him about the similarities with gymnastics and he said you don't see that many styles in gymnastics as you do in figure skating because it's more like theater and many skaters can come up with many different types of music.
The interviewer pulled out his phone and checked Javier's article in Wikipedia and it said that he's one of the few skaters who can perform 2 quads in the same program constantly and he didn't know what that was. Javier explained what a quad consists of and the guy asked if that was a quad Axel, he then explained that the quad Axel has not been performed yet because of the extra half turn. They asked him if he thinks the 4A is possible, and he thinks that maybe at some point somebody will do it because some decades ago nobody would have thought a quad was possible. Then he talked about the combinations and the guy asked him if he knew where he was in the world after landing a quad-triple, and he said that it all depends on how you land.
They asked him what is the jump he struggles with the most (though the interviewer has no idea about any of them except the Axel), and Javi answered the 3Lz and started explaining how to do it but he was kind of struggling with the explanation and the interviewer was having a field day messing with him, That he couldn't wait for Yuzuru to find out. They started simulating the jump and the interviewer injured himself. He said he sometimes struggles with it because he uses a bit of the blade more than the toepick and the judges see that in slow motion, but that he has to do it. They talked about how the judging has changed since the sport started and he asked Javi which was the jump with which he had the worst falling. He said that is was with a quad and started talking about what happens when you don't land backwards and fall head first. But that there are worst ways to fall, for example the flying spin, he said when he was little he fell straight into his chin doing it. The interviewer asked about cutting himself with the blades and Javi said that it happens and even in competitions and used a pairs' incident as example.
They asked him which were the most commonly injured parts of the body and he answered butt and hips. They got distracted by a girl doing an Ina Bauer and the guy asked if there is a chance of a 'Fernandez' and Javier said there should be room for something but that the rules are very strict in terms of creating new things, particularly jumps.
They asked him if he has ever thought about becoming a 'darker' skater, kind of like a bad guy, but he said that's not like he is, that being a World Champion doesn't make him a better person and he doesn't like to brag because he knows someone can defeat him again. The interviewer admits that he was trying to pull out Javier's 'bad boy' attitude but without success.
