CHRIS WHEELER IN CHINA: An under strength Manchester United made a losing start to their tour of China as Borussia Dortmund hit four at the Shanghai Stadium. First-half goals from Castro and a Pierre-Emerick Aubameyang penalty were added to by a stunning third from Ousmane Dembele, before Castro added a fourth after Henrikh Mkhitaryan had reduced the arrears. United went behind after Sam Johnstone could only parry Aubameyang's shot, with the ball eventually falling for Castro to scuff his strike into the ground and over Phil Jones into the net.
