Tottenham slipped to their first defeat of pre-season as they were beaten 2-1 by Bayern Munich in front of a 67,000 sell-out crowd in Seoul.
Son Heung-min, James Maddison and summer signings Archie Gray and Lucas Bergvall all featured for Spurs, who were outplayed by the Bundesliga giants despite the absence of Harry Kane.
Gabriel Vidovic capitalised on a poor pass out from Spurs goalkeeper Guglielmo Vicario to give Bayern an early lead, and Leon Goretzka doubled their advantage after the break.
Pedro Porro's 25-yard strike reduced the arrears but Spurs were unable to find an equaliser against Bayern, who also gave former Fulham midfielder Joao Palhinha a second-half run out.
Ange Postecoglou's side are next in action on Saturday, 10 August, when they will face Bayern again at Tottenham Hotspur Stadium (17:30 BST).
Elsewhere, Newcastle suffered a 2-0 loss to Yokohama F Marinos in the final match of their tour of Japan.
