Juventus claim they have spoken to Pompey about selling them players.
Strikers Fabrizio Miccoli and Marcelo Zalayeta and defender Robert Kovac are said to be among the Juve squad on offer.
Fabrizio Miccoli almost joined Pompey 18 months ago
Juventus officials say they have had meetings with Pompey, Bolton and Middlesbrough.
Pompey boss Harry Redknapp insisted he had not been involved in any talks and had not made inquiries for the players.
But the availability of Miccoli is intriguing.
Pompey agreed a loan deal with Juventus for the forward 18 months ago.
But the 27-old striker preferred to join Benfica on loan instead.
Miccoli scored twice for Benfica in the Champions League this season.
But criticism of his form and weight means Benfica are not expected to push for a permanent deal.
Uruguayan forward Zalayeta, 28,
is said to be surplus to requirements at the Stadio Delli Alpi together with Croatia centre-half Kovac, 32, a free-transfer from Bayern Munich two years ago.
Juve sporting director Alessio Secco said:
'Our mission in England was with the aim of opening contacts with medium-small clubs like Middlesbrough, Bolton and Portsmouth.
'We want to open a relationship with a view to possible sales.'
Redknapp, however, insisted it was news to him.
He said:
'They're obviously all good players, but no-one has spoken to me about anything.
'I've not made any inquiries for anyone.'
