Ig-in's influence is tremendous. After the heat wave, the area around the stadium was crowded with fans from the kick-off time. On the 9th at 8 pm, the 2nd match of the 2026 Coupang Play Series at the Seoul World Cup Stadium between Atletico Madrid and Manchester City will be held. In the 1st match held on the 5th, Manchester City won 3-1 against Team K-League. Ig-in's unofficial debut is approaching. This summer, Ig-in left Paris Saint-Germain (PSG) and put on the Atletico Madrid uniform, one of the three major clubs in the Spanish La Liga. The number 7 jersey and the transfer fee of 40 million euros (approximately 652 billion won) show Atletico's sincerity towards Ig-in. Ig-in's quick integration was made possible by Atletico's efforts, but the administrative procedures for his departure delayed his arrival until June 6. The expectations for Ig-in's performance at Atletico are at their peak. Despite the 2-week-old announcement, over 10,000 uniforms have been sold. Furthermore, fans can see Ig-in's first appearance in the uniform in Korea. Coupang Play has announced that the pre-sale tickets for members have been sold out and the remaining seats are almost sold out. On the day of the kick-off, the area around the stadium was crowded with Ig-in fever. Two hours before the kick-off, the Han River Bridge, which connects the Seoul World Cup Stadium, was severely congested. The World Cup Bridge and the Seongsan Bridge were also congested from the beginning to the stadium. The nearest parking lot, Peace Park and Nanji River Park, were also full for a long time. The traffic police in front of the stadium were deployed in a state of panic, directing the flow of traffic. The subway station at the Seoul World Cup Stadium was also crowded with fans wearing Atletico and Manchester City uniforms. An Atletico fan group even joked, 'There are too many blue colors!' to feel the popularity of Manchester City in Korea. The entrance queue was also longer for Manchester City fans than for Atletico fans. The Atletico fans who have adopted Ig-in have been sufficiently stimulated. The heat wave, which had been intense, also seemed to have helped the crowd. On the 5th, when Team K-League and Manchester City played the Coupang Play Series, the Seoul Metropolitan City issued a top-level heat warning, 'Severe Heat Warning.' The temperature at the kick-off time was also around 35 degrees. The number of spectators was 28,036. Compared to the 60,000-seat stadium, it was a relatively disappointing number. However, the temperature in Mapo-gu on the day of Ig-in's debut was below 30 degrees. The temperature at the kick-off time was around 28 degrees, a relatively comfortable temperature. With the traffic congestion and congestion in the area around the stadium considered, it is expected that the number of spectators will be close to 10,000. 'Ig-in El Nino' is occurring.

The heat wave has subsided, and at this moment, the area around the Seoul World Cup Stadium is only 'Ig-in Debut Fever' is heating up.
