Germany cruised to a 4-0 win over Finland in their final home warm-up before the World Cup, with Deniz Undav scoring twice and setting up another.
Undav terrorised the outclassed Finns alongside 18-year-old Lennart Karl on his Germany debut, but was subbed out with injury after scoring.
Jamal Musiala scored on his return after missing much of the season with a broken leg, while Florian Wirtz also got on the scoresheet.
Finland, ranked 73rd in the world, were little match for the four-time World Cup winners, who have one final friendly before the tournament remaining.
The Germans play World Cup co-hosts the United States in Chicago on Saturday, before opening their campaign against Curacao on June 14.
