Southampton have completed a £1m deal for Swedish international defender Andreas Jakobsson on Tuesday.
Jakobsson performed well for Sweden during Euro 2004
Jakobsson - who was at Danish side Brondby - enjoyed a fine Euro 2004 that brought him to Saints' attention.
Nottingham Forest were keen to buy the defender in July but were put off by the 31-year-old's £1m asking price.
Head coach Steve Wigley said: "He's an experienced player who's a leader and will give us vital experience at the back. I'm delighted he's coming in."
Wigley added: "With Michael Svensson being injured, we are a bit short of experience if Claus Lundekvam was to get injured."
