The LA Galaxy have acquired former Liverpool left-back Emiliano Insua from Stuttgart, the club announced on Thursday.
Insua, 30, will occupy an international roster spot.
"Emiliano is an experienced defender who has played for decorated clubs throughout the world," Galaxy general manager Dennis te Kloese said in a team statement.
"We think he will boost our team on the defensive side and will add a veteran presence to our club. We are glad to add Emiliano to our team and are excited that he will represent the LA Galaxy."
The Argentina international began his career at Boca Juniors, where Galaxy manager Guillermo Barros Schelotto spent many years as a player and manager.
He left the club to join Liverpool, where he was on the books for four seasons. He's also played for Galatasaray, Sporting Lisbon, Atletico Madrid and Rayo Vallecano.
At international level, Insua has made five appearances for the Albiceleste.
