The 33-year-old is expected to earn around €4 million-per-year during his stay in Turin, with the option of an additional year inserted into his contract.
The marauding right-back brings with him a wealth of international experience, having won 89 caps for his country, and is highly regarded by Massimiliano Allegri, who is eager to stamp his authority on Europe.

Alves, who joined the Blaugrana from Sevilla in 2008, will arrive with considerable UEFA Champions League exposure, having lifted the European Cup on three occasions in 2009, 2011 and 2015.
Wing-back Stephan Lichtsteiner has a contract at the club until 2017 and is unlikely to depart the Old Lady of Italian football following the Brazilian's impending switch, with Juan Cuadrado tipped to join former manager Antonio Conte at Chelsea this summer.
Juve will also offer Alves' team-mate Javier Mascherano a two-year deal, however the option of a third will not be included. The Argentine defender is keen to move to the Italian north and talks with his agents have gone smoothly, but an agreement with Barca is still yet to be met.
The European heavyweight clubs enjoy a great working relationship and Juve are hesistent to stretch their correspondence but Mascherano is enamoured with the idea of being allowed to return to a midfield role under Allegri.
