Son was happy to be back in the XI after some injury problems and scored on the day.
He later said: "To be back on the pitch is a joy, playing with my team-mates in a beautiful stadium is one of my favourite things - especially when you get the result.
"When we conceded the first goal he (manager Ange Postecoglou) wasn't very happy. He talked about protecting our goal like a home. But generally altogether with the performance I am very happy.
"When I get the ball I try and find the best solution. In a one-on-one situation I'm very on it and most like to be in this situation.
"(he support is) incredible, I have been missing this support for three weeks and I didn't go to the national team. Playing in front of these fans is a huge honour and I want to give them something back.
"Sometimes injury time can be good, we have such a busy time, that two or three weeks was perfect to recharge myself and today I was feeling really, really good.
"It's entertaining (football under manager Ange Postecoglou) but also a lot of pressure. The winger is expected to create chance and get goals. I think it is a lot of joy and pressure which is where we should be."
