Saracens' squad-building continues apace after they agreed terms with Gloucester to sign prop Carlos Nieto.
The capture of the 32-year-old means that, with Matias Aguero and Fabio Ongaroa already at Vicarage Road, the club will have three Azzurri front rows next season.
Nieto has been capped 31 times for Italy and also made 64 appearances for the Cherry and Whites over the last three seasons.
Saracens director of rugby Brendan Venter said he was keen to welcome a proven international.
"Carlos is a top class tight head who has proved his quality at club and Test level," he said.
"We looked long and hard for the right man with right work ethic.
"In Carlos we have found a player who is widely respected and, just as importantly, who is tried and tested in the Guinness Premiership."
The club have also announced the arrival of 23-year-old Fiji international wing Michael Tagicakibau from London Welsh.
The latest arrivals come after the Guinness Premiership outfit had already announced the signings of Treviso full-back Michael Horak, London Irish prop Richard Skuse and Exeter scrum-half Kevin Barrett.
