Schalke have secured the signature of Greece striker Angelos Charisteas until the end of the season.
The 30-year-old, who started training with the Bundesliga outfit on Wednesday, has been without a club since French side Arles-Avignon cancelled his contract in November.
Veteran Charisteas, who has won 85 caps for his country, arrives at the Veltins Arena as Schalke, currently 11th in the league, look to strengthen their attacking options.
Speaking after his side's 1-0 home defeat to Hoffenheim on Sunday, manager Felix Magath said, with reference to Charisteas: "The defeat showed we still need a head-strong forward."
Charisteas becomes the 34th signing Magath has made since taking the helm at Schalke in July 2009.
The striker, who was part of the Greece squad which won Euro 2004, is no stranger to the Bundesliga, having previously enjoyed stints at Werder Bremen, Nuremburg and Bayer Leverkusen.
