[1] Born in Mont-Saint-Aignan, Stanislas joined Sedan in 2005 and ascending the ranks until finally settling in with the club's under-18 side.
After performing well, he was promoted to the senior squad for the latter part of the 2007–08 Ligue 2 season and made his debut on 28 March 2008, a day after 20th birthday, in a league match against Châteauroux starting the match and playing the full 90 minutes in a 2–1 victory.
After beginning the season in the reserves, he returned to the first team in October 2008 starting in a 1–0 victory over Boulogne.
He was particularly instrumental in helping Sedan reach the quarter-finals of the Coupe de France, where they were eliminated by the eventual champions Guingamp.
Had the match been sanctioned, he would have been tied to France, though rules limited players to only one nationality have since subsided.
