Paris Saint-Germain star Neymar talked up team-mate Kylian Mbappe and believes there is more to come from the teenage forward.
Neymar, who set up Mbappe's goal at Celtic Park, praised the teenager and said the forward would only get better.
"It's always a pleasure to play with great players, even though he's young," the Brazil star said, via UEFA.com.
"For me, he's a great player and he has the potential to improve even more."

An Edinson Cavani brace, either side of an own goal from Mikael Lustig, completed PSG's resounding win.
Neymar was delighted with his side's performance, saying: "Well, it's always very difficult to come here, but we put in a great display as a team.
"Congratulations to all my team-mates. Scoring five goals here certainly isn't easy."
