The Serie A club have had their eye on Paletta for some time but the Boca Juniors player's injury problems had prevented any deal being done.

However, the 24-year-old has now completed his move and will be unveiled tomorrow afternoon, when further details of the transfer will be revealed.

Paletta spent a season at Liverpool but only made three Barclays Premier League appearances, although he did score in the 4-3 Carling Cup victory over Reading, before returning to Argentina in 2007.
