Ulsan Hyundai from South Korea and Mamelodi Sundowns from South Africa are set to face off in the opening match of the FIFA Club World Cup 2025, held in the United States. Ulsan Hyundai, ranked as the second weakest team in the tournament with a team value of only 15 million euros, is known for high discipline and relentless effort, led by coach Kim Pan-gon. Their key player, Brazilian Erik Farias, has scored 8 goals in 14 league matches. Conversely, Mamelodi Sundowns, ranked higher with a team value of 45 million euros, is considered more resilient and capable, with a record of scoring 7 goals in their last 8 matches. Despite their lower FIFA ranking, Ulsan has a strong history against African teams, notably never losing to Cameroon and Senegal in 8 encounters. The teams have not faced each other before, but data suggests both play open, aggressive football with few fouls and corners. Predictions favor Ulsan Hyundai with a likely 2-1 victory, despite the match being considered less competitive due to the teams' rankings and values. The match will be held at Inter Orlando Stadium, with French referee Clément Turpin officiating. Overall, Ulsan's discipline and tactical flexibility may give them a slight edge over the more physically resilient Mamelodi Sundowns.
