Hong Kong is buzzing with football fever as the city hosted the semi-final of the Saudi Super Cup on Tuesday night.

Fans soaked up the raucous atmosphere at Hong Kong Stadium, as the match between Al-Nassr and Al-Ittihad featuring Portuguese football star Cristiano Ronaldo kicked off just after 8pm.

A father, Yousuf, brought his son Jackson to the match to celebrate his birthday and support Ronaldo.

"I think it's fantastic, it's very well organised and the game was fun, and Ronaldo is playing well," he told RTHK.

Another fan, Wood, who also came to support Al-Nassr and Ronaldo, said it was a brilliant game.

"Good atmosphere, the stadium is full, the crowds are enjoying it, so good game," he said.

A fan from Saudi Arabia, meanwhile, said hosting the Saudi Super Cup in Hong Kong is a great way to promote the Saudi culture.

"I think the the Super Cup in Hong Kong is a great experience and will promote, widely promote, the Saudi entertainment, the Saudi Cup around the world," he said.
