Bordeaux on Monday completed the signing of Diego Placente from Argentinian side San Lorenzo.
Les Girondins have not revealed the precise details of the transfer, but the left-back is thought to have penned a two-year deal.
The 31-year-old, who can also fill in at centre-half, passed his medical on Friday but had to bide his time over the weekend before finally being released by San Lorenzo.
Bordeaux coach Laurent Blanc settled on Placente, the former Bayer Leverkusen and Celta Vigo full-back, after a worldwide search for a player to fill the gap left by the departure of veteran David Jemmali.
Blanc was linked with moves for Toulouse's Jeremy Mathieu and Manchester United's Mikael Silvestre but opted for Placente, who has played 22 times for Argentina.
Placente brings with him a wealth of experience, having played for Leverkusen in their 2001 Champions League final defeat to Real Madrid.
