Victoria said about the month or two ago, that in this case their choreographer Galina Ishenko will change her at Worlds and Victor Kudryavzev will help. But Victor Kudryavzev now works with Makarova (in St.Pts) and some pairs (Basarova/Larionov) even not at the rink (or the city) where Korobeynikova trains.
I don`t know anything about Galina Ishenko. Can she help with jumps or no? I dont`t hear anything about Victoria`s assistant. She trains her girls ( Birukova, Shershak and Polina) alone.
So I worry very much about Polina Korobeynikova`s form and skate at Worlds. It`s very difficult task for Polina to debute at Worlds in 15 years old especially in such circumstances.
