I think Scali is working with them mainly, but of course the politics will be handled by her. I think that's the main reason they went to her, and Scali maybe.
Zueva will concentrate on S&K, IMO, because they need to establish themselves in the top 10 (if not even top 5) ASAP. The NA's couples are not waiting for them.
Capellini/Lanotte need to establish themselves for number 1 too. Imagine critiques If they are not on the top after european and world titles season before. Why they did leave Igor?
