Millwall have signed former Lens midfielder Sofiane El Bekri on a one-year deal.
The 18-year-old Frenchman, who has been on trial with the Lions since July, is said to have impressed Ian Holloway and his backroom staff both in training and for Neil Harris's U21 Development Squad.
Harris told the official Millwall website: "We're delighted to give this young man an opportunity to showcase his skills in this country.
"Technically, Sofi is a tremendous footballer and although it may take him a little time to adjust to the English game, his touch, technique and awareness of play around him is first class."
El Bekri's contract also has an option for a further 12 months.
