The agent of Cagliari defender Davide Astori has confirmed an offer from Southampton.

Astori's agent claims his client is interested in a switch to St Mary's, but has made it clear that no agreement is close to completion at present.

Renzo Contratto told Sky Sports: "There is an important offer from Southampton but we don't know if Cagliari want to let him go.

"There is a big difference between the bid and the request of the Italian club, which is about £12million.

"If Cagliari were to accept Southampton's offer, Davide would be willing to consider the proposal.

"He would have no problem going to play in a foreign league such as the Premier League."
