Fiorentina rubbish link for Cagliari keeper Marchetti
Corvino insists the stories have little to do with reality.
"Marchetti to Fiorentina? It's pure fantasy," he responded.
"We are slightly worried about Boruc's shoulder problem and we are evaluating and verifying his condition.
"But our most important signings will be represented by the return of the injured players," he continued. "After all, it's tough to strengthen a squad in January."
