Im not sure this is very wise step from Aliona. Honestly, she is 17 and half. Her top form, even if she would be 100% fit, would last maybe this and maybe next season and then "young rifles" like Kamila, Sofia etc., would simply outperform her, because thats the nature of women figure skating in Russia. But Aliona isnt ok, her health is not good, she long term dont train enough, her skating skills and jumps unfortunately, but logicaly, deteriorated. I dont think she will come back to level on which she was before 2020 and I dont think she will make it to the olympics. I think she is in position of Alina from 2019, means she should "prepare field" for herself in business and shows skating and that mean avoid any more scandals and just calmly working on her skating. Plushenko is maybe not good coach, but he have conections and rich friends in bussines and entertainment sphere in Russia. If Aliona dodnt consult and decently communicate with him her decision and now puting his academy into bad light, it can have consequencies on her skating carrier after she left competitions.
Anyway, I wish her all best and mainly good health.
