The 21 year-old has been linked with a January move to Lazio.
Fabiani told Lazio's website: “Fazzini is an excellent player, our scouts have monitored him but we have also met him. I want to say one thing, the market is not made by social media and not even Fabiani does it alone.
"A series of convergences are needed, I will name one above all. When we signed Dele-Bashiru, if there had only been Fabiani's opinion the percentage of his arrival would have been low. However, we met with the scouting area, with my right-hand man Bianchi and Baroni and we saw some qualities, the boy is giving us answers on the pitch and this will apply to everyone, not just Dele-Bashiru.
"I don't like a man alone in command, I like to share and compare myself with everyone. Fabiani didn't invent football, today a fan knows how to understand if the player is good or not. This is my modus operandi."
