Leyton Orient boss Russell Slade has revealed that Yohann Lasimant has signed a one-year deal with the club.
The 23-year-old, who departed Larissa at the end of last season, has three France Under-20 caps to his name.
"Yohann impressed us on trial and though he had one or two other options on the table, he enjoyed his time here and we're pleased to have him sign," Slade told the club's official website.
"There's still a bit of work to be done with him but he's got good pedigree and has shown good potential plus he's capable of playing in a couple of positions as he can play wide or off the striker."
Lasimant began his professional career with French outfit Rennes.
