The highly rated son of football legend George Weah has scored two goals in six first-team appearances for the Ligue 1 champions and becomes the Bhoys' second loan signing of the January transfer window following the arrival of West Bromwich Albion winger Oliver Burke.
The New York-born forward, just 18 years old, started the 2018-19 season with a bang, filling in for Neymar and Kylian Mbappe after their World Cup exertions, but has found playing time difficult to come by after the pair's re-entry into the starting XI.
Despite scoring a goal for every 72 minutes he’s been on the pitch this season, Weah has enjoyed far more playing time with the United States Men's National Team, taking in eight appearances and scoring one goal since his debut in March 2018.
In a statement released on Celtic's official website, manager Brendan Rodgers said: “Timothy’s a young talent who is full international player. He has a long career ahead of him but he has those natural attributes in terms of his pace and technique. He’s hungry too.

“He’s been in the PSG squad and featured for them in pre-season. With the quality of players they have, it’s difficult for him to get in and get any game-time. They wanted him to go out on loan and saw Celtic as a great possibility.
“He has really good qualities technically, and tactically is always improving his game. Physically he’s very good, very fast and is a strong player. He’ll add competition to the squad.”
The signing of Weah will provide a big lift for Hoops fans, who saw their side go level on points - albeit with a game in hand - with Glasgow rivals Rangers after their most recent Old Firm meeting.
The win was seen as a turning point for the Gers, who had spent years clawing their way back up the Scottish league system following administration problems.
Rangers' recent signing of Jermain Defoe on an 18-month loan from Bournemouth and the prospect of Steven Davis' return to Ibrox means Weah's arrival goes some way to matching their eternal rivals' clever movement in the January window.
