Apparently the news about Kosheleva was a hoax. She's not in Scandicci's roster on LVF site and also the commentators said something like somebody from Scandicci answered the question about Kosheleva arriving with "That's Fantavolley".
" After the end of the season I received several offers from different clubs to continue the season. And I, after consulting with my family and the Brazilian club, which I played for, decided to go to Italy to the Scandicci club. I want to say thanks to the Rexon-Sesc club, that they supported me in this "- said Kosheleva.
