I still think Kosheleva will make it to Tokyo, especially now she is back playing in Russia so the Federation will definitely put pressure on Buzato to consider her (if only due to her experience). No question she will be the best candidate in the double sub, compared to say Khaletskaia or God forbid, Malygina. Only question if she will allow to be backup to Goncha
They should be preparing for Gonchexit so Lazareva might need the olympic experience.
Anyway, they need a good server because Nataliya's serve is... weak. She needs someone who could cover for her during that phase without sacrificing a lot of firepower.
