Alberto de Marchi will join Sale Sharks on a two-year contract at the end of the season.
The 28-year-old Italian loosehead will arrive as a replacement for the Bath-bound Henry Thomas.
De Marchi, who has played 17 times for Italy, will link up with fellow new recruits Chris Cusiter and Nathan Hines at Sale next season.
Director of rugby Steve Diamond said: “Alberto has just had a very good Six Nations with Italy. A lot of work and due diligence has gone into signing him. We’ve watched him both with Italy and before in his club games with Treviso. Toulon tried to sign him but fortunately, we’ve been able to bring him here.”
“I’ve no doubt he’ll prove to be a really big asset for us over the next few years.Alberto is a good scrummager, he is very mobile around the pitch, he’s also a good defender and we’re very happy to have him on board.”
