Neymar, Lionel Messi and Kylian Mbappe all scored as Paris Saint-Germain overpowered Gamba Osaka 6-2 on Monday to wrap up their preseason tour of Japan with three straight wins.
After beating two-time defending J. League champions Kawasaki Frontale 2-1 on Wednesday and Urawa Reds 3-0 on Saturday, PSG had their best offensive return at a full Panasonic Stadium Suita against a Gamba side fighting relegation from the Japanese top flight.
Gamba keeper Masaaki Higashiguchi could do little to stop Pablo Sarabia from finding the net in the 28th minute after initially saving from Messi.
Neymar won a penalty and converted from the spot four minutes later before Keisuke Kurokawa tapped in a loose ball for Gamba in the 34th minute following a cross from Kosuke Onose.
PSG responded immediately, however, as Nuno Mendes blasted home from a tight angle, and Messi steered in a Neymar cross to give the visitors a 4-1 lead at the break.
Messi returned the favor for Neymar on the hour mark after playing through the Brazilian, who rounded Higashiguchi to score his second, before Gamba grabbed its second 10 minutes later through substitute Hiroto Yamami.
But substitute Mbappe made sure he also got on the score sheet, by winning a penalty and burying it himself four minutes from time.
"A chance to face these players doesn't come around too often. I was determined to score if given a chance to play," Yamami, said.
Defender Gen Shoji, who had a spell at Toulouse in France, said: "I'm sure we all felt something as individuals. It's about how much we can use that for the better."
PSG will begin their Ligue 1 title defense away to Clermont on Aug. 6, while Gamba is back in J1 action on Saturday at home to Kansai rival Kyoto Sanga.
