Genoa insist Independiente defender Julian Velazquez is their player.
Velazquez was signed over the summer, but he returned to Argentina when Independiente claimed they had not received the full payment.
"I think Independiente have a financial interest in not registering the player for us, but in the end the transfer will arrive and everything will be resolved," Genoa President Enrico Preziosi told Sky Sport Italia.
"After all, Velazquez is definitively a Genoa player."
