Werder Bremen have signed former France defender Mikael Silvestre on a free transfer.
The 33-year-old, who was without a club after leaving Arsenal at the end of last season, has signed a two-year contract.
Silvestre, capped 40 times by France, began his career with Rennes, where he caught the eye of Inter Milan. After a short period at the San Siro, he moved to Manchester United in 1999 where he enjoyed a successful nine-year spell. In his time at Old Trafford he won four Premier League titles, one FA Cup and Champions League.
He moved to rivals Arsenal in 2008 following a season during which he suffered knee ligament damage, however he seldom looked comfortable in the Gunners' backline and struggled to win over the fans.
Silvestre, who can play at full-back or in the centre, reportedly shunned Fulham and Kayserispor to join Bremen.
"I want to be one of the leading players in the team and to help guide the younger players," he said today.
Schaaf added: "He is still hungry for success. I'm sure our players will benefit from him being here. He's an asset."
Bremen, who lost star man Mesut Ozil to Real Madrid this summer, have begun the Bundesliga season with one defeat and one win.
