Corvino shuts the door on Insua...
Negotiations between Fiorentina and Liverpool had progressed well, but questions over the player's wage demands have scuppered the deal, and the Italians have pulled out.
"Insua? It has been a transfer that has gone on for a long time because of the player," he told the press.
"I had dinner with Liverpool's sporting director until two in the morning. The player is staying at Liverpool.
"The reasons are linked to the player. His demands are high for us. We will not sign Insua."
Corvino also confirmed Juan Manuel Vargas is staying at the Artemio Franchi, despite being linked with Real Madrid and Inter.
"If players don't ask to leave then we will keep them. We want to keep all our players. Vargas? He is staying," said the chief.
