Gianluca Vialli's consortium has pulled out of talks with Sampdoria.
Vialli had been heading the Calcioinvest consortium, which included Jamie Dinan and Alex Knaster as backers.
The group say Samp president Massimo Ferrero is asking too much.
A released statement read:
“At the end of a long and careful due diligence process, carried out with enthusiasm and professionalism, Calcioinvest considered the current financial demands to be excessive."
