Fluminense RJ vs Ulsan HD FC Prediction, Preview, Standings: 21/6/2025

Fluminense return to the Club World Cup amid high expectations as Copa Libertadores champions, competing in a revamped 32-team tournament taking place in 12 American venues between June 14 and July 13. They face Ulsan HD FC from South Korea in their Group F fixture on June 21 at 18:00 ET in New Jersey, kicking off a group that also includes Borussia Dortmund and Mamelodi Sundowns.

Fluminense go into the match with a strong record, remaining unbeaten in five games—four wins and a draw—including a scoreless draw against Borussia Dortmund, underscoring their tactical discipline and defensive resilience . The club recently appointed Renato Portaluppi (Renato Gaúcho) as head coach in April, marking his seventh tenure and aiming for continental and global success.

In contrast, Ulsan HD progressed as Asia’s top-ranked club and Korean champions, entering a challenging group with the goal of reaching the knockout phase. They appointed experienced manager Kim Pan-gon a year ago; under his leadership, they secured their continental title in November despite an overall win rate under 50%. The coach has expressed clear ambition of advancing to the Round of 16.

Match Outlook and Tactical Insights

Fluminense’s recent unbeaten run and strong squad depth make them favorites. Their matches have shown a fluid blend of attacking potential and defensive robustness, guided by Portaluppi’s possession-oriented and transition-focused strategy. Their draw with Dortmund illustrates their capacity to compete with top European teams.

Ulsan HD FC may enter as underdogs but carry determination and tactical cohesion into the showdown. Kim Pan-gon’s pragmatic approach aims to keep the match tight, relying on disciplined defending and opportunistic counter plays. Despite their defensive strengths, their scoring record has been inconsistent, which could be exploited by Fluminense.

Considering the form and quality gap, a Fluminense win appears probable. Odds reflect this with a strong favorite status at 1.27, a draw at 6.01, and a Ulsan upset at 13.30. A bet against both teams scoring could also hold potential, with a “No” for both to score offered at around 1.57 .

The tournament format, mirroring a mini World Cup, gives each group’s top two teams entry to the Round of 16. Group F is particularly competitive as UEFA and CONMEBOL sides dominate overall predictions . Prize incentives are substantial—clubs earn millions per win, with total tournament prize money hitting nearly $1 billion
