Gabriele Angella has left Watford to sign a new contract with Udinese until June 2020.
The two clubs are both owned by the Pozzo family, so they regularly move players to and fro.
A statement confirmed Udinese have bought back the rights to Angella on a permanent basis.
He signed a new deal holding him to the Friulani until June 2020.
The 27-year-old had been in England since July 2013 at Watford and also a spell on loan at QPR.
