The incident came on the back of Juve’s 3-3 friendly draw with Team K-League in the Korean capital at the end of July, when former Manchester United and Real Madrid icon Ronaldo failed to make it off the substitutes' bench.
His no-show enraged fans who had turned up to see the Portuguese superstar in action, and the K-League accused the Italian champions of “deception” – a claim that was shot down by Juve.
A criminal complaint was filed against Ronaldo, Juventus and the South Korean agency that organised the fixture, and a police investigation is underway – but one fan took matters into his own hands by following Ronaldo to Stockholm.
Kwak, who posted a lengthy video of the meeting on his YouTube channel that has reached almost three million views, shouted in English: “Why didn’t you play in Korea?”
The question was ignored but Kwak made several more efforts to get Ronaldo’s attention, including holding up a sign in Portuguese.
"Even when I put the sign right in front of his eyes, I was utterly ignored," Kwak says in the video.
"You are so nice to your fans here but why did you do that to us?" he added.
