United's second game of their much-ridiculed tour of the Far East got off to a nightmare start when Juninho beat Tom Heaton at his near post to give Hong Kong the lead with their first shot of the game after a dominant start from United amid persistent rain. Bruno Fernandes and Alejandro Garnacho might have played their last games for the club in a frustrating first half in which Casemiro had a goal ruled out for offside. Ruben Amorim changed his entire starting XI for the second half and Obi dug them out of a hole, scoring twice before Ayden Heaven, his former team-mate at Arsenal, made sure of the victory in added time.
