Post Worlds TV interview with Denis after his arrival in Kazakhstan (in Russian): http://bnews.kz/ru/videonews/post/130108/
He talks about how important it is for him to show the world where Kazakhstan is, comments on how his former coaches (Elena Buianova, Tatiana Tarasova), other athletes (including Evan Lysacek, Evgeni Plushenko) congratulated him.
He said that probably this was his best performance to date but there is no limit for perfection and he has a lot of work ahead of him. He mentioned a new fitness trainer in Calgary. He talks about how Frank Carroll motivated him for Worlds after the tough start of the season and how upset he was to hear at one event that he is "a skater from a country that doesn't exist". Then he promised to himself that he would make Kazakhstan known to the world. Well done, Denis!
