As expected, Fulham midfielder Sylvain Legwinski has signed the contract offered by Town at the end of his recent trial. The 33-year-old has committed to staying with the Blues for two years.
Boss Jim Magilton told the club site: "We're delighted that Sylvain has agreed to join us.
"He has played at the highest level for many years now and will bring with him a wealth of experience from that time.
"He's a good passer, is strong on the ball, adds to the height in the team and can play right across the midfield. I'm sure he will prove to be a great acquisition for this football club."
Legwinski joined the Blues on trial at the start of last week and played 45 minutes of the behind-closed-doors game with Spurs which the Blues lost 3-1.
Nicknamed Monica by Fulham supporters, Legwinski was previously on trial with French club Troyes but failed to win a deal.
The busy defensive midfielder joined Fulham from Bordeaux for £3.3 million in August 2001. Born in Clermont-Ferrand, Legwinski has made 148 starts and 16 sub appearances for the Cottagers and scored 12 goals.
Prior to his two-year spell with Bordeaux, the midfielder started his career with Monaco. Legwinski is known for his Matt Holland-style applauding of fans at the end of matches.
Made available on a free transfer by Fulham boss Chris Coleman despite having a year left on his contract, Legwinski looks to be a replacement for loanee Simon Walton when he returns to Charlton at the end of his month at Portman Road.
