Fiorentina have blasted Inter Milan striker Hernan Crespo as the Argentine prepares to join Genoa.
"Someone is trying to be sneaky, I already have an agreement and I want it to be maintained," Fiorentina director Pantaleo Corvino said.
"If they want to play at creating a bidding war, they are sadly mistaken. We had a formal deal, even if there was no paperwork, but we certainly will not accept an increase in the figures we already agreed."
Corvino launched a particularly scathing attack on agent Fernando Hidalgo, who represents Crespo.
"I have not been called by the agent or the player. One thing is certain, I won't let anyone take the mickey out of me and I am not lacking in imagination when it comes to buying players.
"We have Alberto Gilardino and can wait for the right man to come along. We've no emergency to get a centre-forward."
