The American youngster has only played in the United States youth system and in the French Ligue 1 club Paris Saint-Germain.

18-year-old Timothy Weah was loaned from the French Ligue 1 team Paris Saint-Germain to the Scottish Premier League side Celtic.

The young American striker grew up in the United States football youth system with West Pines United, Blau-Weiss Gottschee, and New York Red Bulls.

He then moved to France to play in the PSG youth squad from 2014 to 2017.

And in 2017, he was called up to the B team, only to win a chance in the senior squad the next year.

Now he has been hired by Celtic for the next six months.

“It’s a bit more physical here and at training, we go all-in,” said Weah to Celtic’s official website.

“The style of play is really fast and really physical. That’s the difference I’ve noticed is the physicality.”

“It’ll help me in my career because I know, whatever league I play in, I don’t think it’ll be as physically tough as the Scottish league.”

Celtic is a little flat: Neil Lennon

The team drew 0-0 against Aberdeen in today's Scottish Premiership fixture but keep the league's first position.

“As an 18-year-old it’s good to get that experience and get used to dealing with that feeling of guys challenging you hard and learning how to handle that and play with that challenge,” he added.

“I’m settling in really well,” he commented after scoring on his debut.

“Everyone has made me feel really comfortable. This team is more of a family than individuals. It was easy for me to come in and get well-acquainted with the boys.”

“Having some French friends here too has been great. I played with Odsonne at Paris Saint-Germain, so I already knew him and being fluent in French has made it easy to get to know the other French boys,” he added.

“There are really no egos in the dressing room. Everyone’s competitive and it’s a good vibe, so we all get on.”

“I saw right away just how important a captain Scott Brown is. He’s amazing on the field but what a lot of people probably don’t see is how important he is for the dressing room. He’s crazy, he makes everyone laugh and really brings us all together,” he concluded.
