The 19-year-old forward who is the son of Ballon d’or winner and Liberia President, George Weah, moves to last season’s second placed team for a sum believed to be in the region of £9m.
Battling for a place in a PSG side that features the likes of Neymar, Kylian Mbappe, Edinson Cavani and Angel di Maria was always going to be a herculean task for Weah as he spent the second half of last season on loan at Scottish champions Celtic.
Weah scored four goals in 16 games during his loan spell in Scotland until his season was cut short when he was selected to feature for the United States in the u-20 FIFA World Cup, where they exited at the quarterfinal stage.
“Welcome Timothy Weah! a tweet on Lille’s twitter handle read.
“LOSC have reached an agreement with PSG for the services of the USMNT international forward, who arrives at the StadePM on a five-year deal.”
By virtue of their second placed finish, Lille will be playing Champions League football in the 2019/2020 season.
“For me LOSC is the best choice to progress and earn playing time,” Weah said in a statement.
“It’s a young and ambitious team, I know that [head coach] Christophe Galtier and his staff are very professional and appreciated by the players.
“Joining LOSC is a big deal, this team had a great season last year, finishing second is a great performance, playing in the Champions League is also a dream that I will be able to achieve.
“I want to score goals in my new colors and help this club to win games and trophies.
