Warriors sign Faosiliva
The flank becomes Warriors' seventh new signing ahead of the new season.
He spent much of his early career on the international Sevens.
Faosiliva was part of the Samoan side that won the Sevens World Series in 2009/10.
"Warriors is an ambitious club with a clear vision which is something that really appealed to me," Faosiliva said.
"The set-up at Sixways is fantastic and everything is in place for you to succeed as a professional rugby player.
"Now I just can't wait to get started and I'm hungry to get out there and compete for my place in the team."
The powerhouse then had spells at Toulon and with Premiership side Bath where he spent three seasons.
The 30-year-old also has 18 international caps to his name with two of those coming at last year's Rugby World Cup.
Head coach Carl Hogg added, "Alafoti is a great athlete and his versatility will add greater strength and depth to our back row.
"He is a big ball-carrier with international experience. Those are key attributes which will stand him in good stead ahead of the new campaign so we're excited about seeing what he can do out on the pitch."
