Huntelaar easily received the ball near the baseline, while Domingos and Antonio López both raised their right arms to signal offside, but the referee's whistle did not sound.
Because the assistant referee saw very clearly that at the moment when Huang Kaiwen passed the ball, Huntelaar was not in an offside position.
The two didn't defend immediately but instead raised their arms, which made them miss their last chance.
Huntelaar turned and returned the ball with a back pass, Domingos already rushed towards the ball, but he was still a step too late, as Huang Kaiwen took it first with the inside of his foot.
Running to the goal to defend, Santana turned and bent his leg, allowing the ball to fly right through the crook of his knee. A sight-obstructed Assuncao was already too late behind, and could only watch as the ball went into the net again by his hand.
After scoring, Huang Kaiwen opened his arms to embrace Huntelaar, who provided the assist.
