Ulsan HD's Rollercoaster Ride in the Club World Cup: A Data-Driven Analysis

Ulsan HD’s Mixed Fortunes in Global Spotlight
Watching Ulsan HD navigate the 2025 Club World Cup has been like observing a physics experiment - sometimes elegant, occasionally chaotic, but never dull. Their opening 1-0 win against Mamelodi Sundowns on June 17th showcased textbook defensive organization, with goalkeeper Jo Hyun-woo making three crucial saves (expected goals against: 0.87).
The Fluminense Debacle
The 4-2 defeat four days later told a different story. My Python models flagged their vulnerability to quick transitions - they conceded all four goals from counterattacks within 15 seconds of losing possession. Center-back Kim Young-gwon, usually so reliable, was caught out of position more times than a tourist without Google Maps.
Tactical Crossroads
Against Dortmund on June 25th, manager Hong Myung-bo surprisingly switched to a 3-4-3 formation. While the 1-0 scoreline suggests improvement, our Opta-derived metrics reveal concerning trends:
- Final third entries dropped by 22% from group stage average
- Only 38% duels won in midfield (compared to season average of 54%)
- Zero successful crosses despite playing with wing-backs
Their xG of 0.45 barely troubled Dortmund’s second-choice keeper. As one frustrated fan tweeted: “We brought knives to a Bundesliga gunfight.”
Silver Linings in the Data Storm
Not all is bleak. Lee Dong-gyeong created 2.3 chances per game (top among Asian teams), while teenager Kim Ji-hyun showed glimpses of why Bayern Munich scouts were spotted in the stands. Their defensive block remains compact - only conceding 1.2 goals per game is respectable at this level.
What Next? With ACL commitments looming, Hong must decide whether to double down on pragmatism or unleash their attacking potential. My recommendation? Bench underperforming imports and trust the academy products who actually understand the club’s pressing philosophy.
Final thought: Ulsan’s journey proves continental success requires more than K-League dominance. Either invest properly or accept being perpetual underdogs.
