David Moyes's reign as Manchester United manager has got off to a losing start as the Premier League champions were beaten 1-0 by a Singha All Star XI in Bangkok.
Rio Ferdinand, Jonny Evans, Michael Carrick, Ryan Giggs and Danny Welbeck all featured in the first half for the Red Devils.
Chances were few and far between during the opening 45 minutes, but the visitors' best opportunity came through Belgian youngster Adnan Januzaj when he clipped his shot over the crossbar.
The home side made the breakthrough five minutes into the second half as Teeratep Winothai burst into the area before driving the ball low past Ben Amos.
Wilfried Zaha came on for United midway through the second period and nearly scored an equaliser when his effort came back off the woodwork.
Despite some late pressure and openings for Welbeck and Januzaj, the visitors failed to find an equaliser.
