SECOND HALF - OBI OVERTURNS IT
It took only five minutes for the Reds, with a completely changed XI, to get back onto level terms, as Obi scored with a slick finish. Kobbie Mainoo worked the ball towards Manuel Ugarte and he touched it into the youngster's path, with the centre-forward displaying neat footwork before firing home a low drive.
Tse was at full stretch to keep out a fierce drive by the lively Mason Mount, who then crossed well for Obi to send a header wide at the near post.
With 67 minutes on the clock, Mount's free-kick was begging for a finishing touch to be applied, but Ayden Heaven's header only took it across goal and Hong Kong, China survived another real scare.
Seconds later, the hosts produced a rare break of genuine threat but Lau Cheuk-hin's attempt was kept out impressively by Altay Bayindir.
Obi produced a similar effort to his goal, only to be thwarted on this occasion by a decent stop, and Mount's penalty appeals were turned down, when he was brought down inside the box, as United looked for a winner.
With only eight minutes of normal time remaining. Mount was again the orchestrator, with a clever chip into the area, and Obi's glancing header found the bottom corner for his second goal of the game.
Heaven got on the end of an Amad centre to nod a third, in the dying seconds, to provide a 3-1 scoreline United's performance merited.
It ensured a winning end to the post-season tour and signed off for the 2024/25 campaign on a positive note for the teenager.
