French forward Antione Griezmann made his Barcelona debut in a 2-1 defeat to Chelsea as part of both teams' pre-seasons in Saitama, just outside of Tokyo, on Tuesday.
The €120m ($134m; £107m) star was on the receiving end of a heavy challenge from Jorginho early on but was able to complete the rest of the half.
"He has yet to get used to our game, but you can see that when he has the ball, it is very dangerous for our opponents," said Barcelona coach Ernesto Valverde. "He always has dangerous ideas for the opponent and we expect a lot from him."
Chelsea ran out victors thanks to two goals from English duo Tammy Abraham and Ross Barkley, while Barca's Ivan Rakitic scored a consolation in additional time.
New boss Frank Lampard revealed afterwards that Griezmann's compatriot N'Golo Kante had returned home for treatment on a knee injury.
"It's not a big backwards step that has been taken. He's improving and hopefully we will get him back by the time we start training towards the weekend," he said.
