Manchester United suffered their second defeat in three pre-season matches as J League outfit Yokohama F Marinos struck late to beat David Moyes' men 3-2.
Jesse Lingard had scored another goal to continue his impressive run of form but despite holding a half-time lead, United were unable to keep their advantage.
In the stadium where they won the World Club Cup in 2008, not even the introduction to great acclaim of Shinji Kagawa, who amazingly was named man of the match, could inspire United to victory, with Yoshihito Fujita netting the winner three minutes from time.
Having named a youthful starting line-up, manager Moyes must have been delighted at the manner in which they responded to a quite unexpected early setback.
Their hosts piled forward straight from the kick-off but when David de Gea produced an acrobatic save to deny veteran Brazilian striker Marquinhos, United thought they had been let off the hook.
Instead, they struggled to regroup and when the ball was played back into the box, Marquinhos, the 37-year-old, was on hand to turn it home with a first-time effort.
Not even half a minute had been played.
It must have been a substantial positive for Moyes that none of those young heads went down.
Indeed, two of them combined to haul United level after 18 minutes.
Lingard scored twice in Sydney on Saturday and is evidently in form.
