Longo also has an offer from Hellas Verona.
"We already have a deal for Longo, but the player has taken time to reflect," Livorno director of sport Stefano Capozucca told La Gazzetta dello Sport.
"We can only wait a few days, but no more than that. Players coming to Livorno must arrive with the right mentality. They have to know what type of campaign they'll have here and what spirit they must adopt."
