A two-time Premier League winner during his time at Chelsea, Cudicini comes to the Galaxy after spending more than a decade competing in the Premier League, first with Chelsea from the start of the 1999/2000 season until January 2009, when he joined Tottenham, where he has been ever since.
The 39-year-old, who was also on the roster of Italian sides AC Milan, Lazio, Como, Prato and Castel do Sangro during his professional career, played the full 90 minutes for Tottenham in their friendly against the Galaxy at The Home Depot Center in July.
"We are delighted to be able to add Carlo Cudicini to our roster," Galaxy head coach and general manager Bruce Arena said. "Carlo is an experienced and accomplished goalkeeper who we believe will be a great addition to our team and our defensive unit."
LA will be making its second straight CONCACAF Champions League quarterfinals appearance this March, when it faces Costa Rica's Herediano.
