Mbappe scored four goals, including in one France’s 4-2 win in the final over Croatia, to win the tournament’s Best Young Player award.
Buffon, who joined PSG this summer, says the young Frenchman has the potential to be one of the game’s greats.
“Kylian has something more than the others,” he told PSG’s official club magazine. “I hope that he will remain humble and maintain his desire to progress and make sacrifices.
“If Kylian does that, then he will leave his mark on football history and write some incredible pages in sporting history.”
While the two are yet to play together as teammates, they have played against each other before, when Mbappe inspired Monaco to a Champions League semi-final berth in 2016-17 before Buffon’s Juventus put an end to their run.
But the young star served enough notice of his talent in that tie, with Buffon saying his then teammate Andrea Barzagli revealed just how difficult Mbappe makes life for opponents.
“When I spoke with Andrea, one of my great friends, at the end of the match, he told me: ‘Gigi, in my 20 years as a professional football player, I have rarely seen somebody so fast and so quick even with the ball – I had trouble marking him’,” the legendary goalkeeper recalled.
“These words are not trivial. Andrea, when he is focused and on song, is a great defender.”
Angel Di Maria‘s double fired PSG to their first silverware under new coach Thomas Tuchel as Neymar, long sidelined by a metatarsal fracture, came on as a late substitute.
Di Maria’s thunderous free-kick opened the scoring on 33 minutes and he grabbed PSG’s fourth in injury-time following strikes from Christopher Nkunku and Tim Weah.
PSG, with their names in Chinese characters on the back of their shirts, were the aggressors and they took the lead via Di Maria’s sumptuous dead ball play on 33 minutes.
The Argentina forward swept over the wall and into the top-right corner from 25 metres, evading Diego Benaglio’s despairing dive.
As Tuchel watched while sitting on an ice box in the technical area, Nkunku made it 2-0 on 40 minutes with a close-range finish from Stanley Nsoki’s inviting cross.
Weah went close and Di Maria then left Benaglio nursing sore fingers with a powerful drive near the break as the French champions went into half-time firmly in control.
In the 67th minute, Weah put the win beyond doubt when he stroked home Nsoki’s lay-back, before Nkunku rattled the crossbar from close range shortly afterwards.
There were loud cheers from the 41,000-strong Shenzhen crowd when Neymar was introduced on 76 minutes but the world’s most expensive player, last seen in Brazil’s World Cup quarter-final loss to Belgium, couldn’t add to the scoresheet.
Di Maria, deservedly, had the last word when Adrien Rabiot‘s long run set him up for an easy finish which he slotted past the beleaguered Benaglio in the third added minute.
Christopher Nkunku put the French side ahead in the 32nd minute and Moussa Diaby doubled the advantage in the second half before Victor Carpintero Mollejo scored for Atletico in the 75th minute.
Antoine Bernede then put the ball into his own net four minutes before the 90th minute mark as the scoreline stood at 2-2.
However, Postolachi’s curling shot in added-time could not be stopped by Atletico goalkeeper Antonio Adan as Diego Simeone’s men lost 3-2.
Below are a look at all the goals from the encounter.
