Jose Mourinho suffered his first defeat as Manchester United manager as his side slipped to a 4-1 defeat against a classy Borussia Dortmund in the International Champions Cup on Friday, Goal.com reports.

Dortmund, who were competing in their fifth pre-season affair compared to United’s second, made their extra sharpness count as they raced into a two-goal lead in the first half in Shanghai.

Gonzalo Castro stabbed home a scrappy opener and Pierre-Emerick Aubameyang scored a penalty after Antonio Valencia handled inside the box, before new boy Ousmane Dembele scored a fine solo effort to stretch the lead after the break.

Henrikh Mkhitaryan, who joined United from Dortmund earlier this month, scored his first goal for the club to reduce the arrears, but Castro’s classy long-range finish restored his side’s three-goal cushion.
