That is a big if, especially with Trusova. Perhaps I am less cynical about judging, but if Rika skates clean, I predict she will be on the podium.
The one thing that Eteri has shown is for her skaters to be in good shape for Worlds. Remember last season with Alina? Her form at Worlds was much different to that at Euros or Nationals.
That said, I have faith in Rika, just not the judging.
