Cagliari president Massimo Cellino admits they need to keep buying during this month's market.

"We aren't in a good situation. Our League position is worrying and we need reinforcements," he told Radio Kiss Kiss. "Napoli don't want to sell Nicolas Amodio or Roberto De Zerbi unless we pay a fee that is out of proportion.

"It was basically their way of saying no and that we should be looking for other players.

"Last summer we were all set to sign De Zerbi, but their sporting director Pasquale Marino assured us that he was part of their plans.

"The lad has been left out and yet they are asking for a higher sum now."
