Weah believes competition for places will work wonders for his development
Weah struggled for playtime at PSG in the first half of the season and joined Celtic in a six-month loan deal.
The 18-year-old United States international has made an instant impact at Parkhead, scoring two goals in two games since he joined the Scottish champions.
And Weah believes that his experience of training with some of the best players in the world at PSG will help him in his development.
“Obviously at PSG they have the best players in the world,” he told the Press Association.
“Being with that group has really made me strong. I have watched the ins and outs of everyone, Neymar and Mbappe and all those guys in training and I really feel that it has moulded me into a stronger person and a fighter and it made me a lot hungrier than before.
“I don’t see it as being much different [at Celtic], we are human beings and we are all fighting for the spot and everyone has that hunger and once you have that hunger you can do what you need to do.
“The competition here is great, Sinky [Scott Sinclair] and James Forrest are top-class players and getting the chance to compete with them and train with them every day is going to make me a better player.”
