Greece captain Giorgos Karagounis has signed for Fulham on a free transfer until the end of the season.
The 35-year-old midfielder was a free agent after leaving Panathinaikos at the end of the 2011-12 campaign.
He said: "I'm delighted to have signed for Fulham and I am excited by a new challenge in England and the Barclays Premier League.
"I'm looking forward to working under Martin Jol and playing alongside some fantastic players at this club."
Jol said: "Giorgos has a wealth of club and international experience and I'm happy that he's joined us for this season.
"He's been an influential player for his club sides and is a renowned player in world football as he's about to become the most-capped player for Greece. He brings many certain qualities to our squad."
