Nigel Adkins’ men have long been rumoured to be interested in the towering centre-half, along with Italian giants Napoli.
Astori has two international caps for Italy to his name and is a product of the world-renowned AC Milan youth set-up. Uncompromising yet technically sound, Astori would provide great steel to a wobbly Saints back four.
The South Coast club have struggled defensively all season, though they are starting to look more assured at the back as the season progresses.
However, that apparently hasn’t stopped Adkins and club chairman Nicola Cortese from seeking out a top defensive talent from the continent.
Southampton have already spent over £33 million in the summer transfer window. And it seems the Hampshire outfit are looking to splash the cash once again to ensure Premier League survival.
The agent for the £8 million-rated Astori, Renzo Contratto, is quoted by Sky Sports:
There are many clubs interested in Astori and among them I know there is also Southampton.
Both the player and Cagliari have said in the last days that, in the event that an important offer came, they will evaluate it together and decide what to do. This could happen in January.
Back in July, the Italian stopper rejected a move to Spartak Moscow in favour of staying in Italy after a rumoured £12 million bid was accepted by the Rossoblu.
Cagliari are currently in a relegation dogfight of their own. But the cash-strapped Sardinians appear to be willing to profit from one of their few shining stars of the present Serie A campaign.
