Livorno have warned the next two days “will be decisive” for Dynamo Kiev’s Artem Milevsky.
The negotiations for the 28-year-old Ukraine international striker have continued for several weeks, but have hit problems.
“Tomorrow and the day after tomorrow will be decisive,” said Livorno President Aldo Spinelli.
“The Dynamo Kiev President does not want to unblock the negotiations. We are trying everything possible, but are also working on other options.
“If Milevsky does arrive, then we’d have a few too many players in attack. Tomorrow is the last day to close the deal. If he is not freed, then we will give him up.”
Spinelli also confirmed that “Leandro Greco, Samuele Longo and Alfred Duncan  are possibilities.”
Longo and Duncan are owned by Inter, while Greco is at Olympiacos.
