Ksenia Gushchina's choreographer (for one of the new programs) was Aleksandrina Degtyareva, her coach, Kirill Davydenko said in an interview.
"By the way, this year we did not invite choreographers from outside. We did the programs ourselves. First of all, I think we should give way to the young. And I see that the guys can do well, that it is like a challenge for them, because you work with the skaters of the national team, the national team of our city. For example, Aleksandrina Degtyareva made a program to Ksyusha Gushchina. Very good. You'll see," said Kirill Davydenko.
Short program or free skating, he didn't specify.
I want to add from myself personally that Ksenia and Aleksandrina work a lot on the choreography in the programs, especially steps sequence. They get the help of popular Russian choreographers. In my opinion, Ksenia has made great progress in this direction.
