Serhou Guirassy’s 2024/25 season was phenomenal. Across club and Guinea national team appearances, the striker was directly involved in 47 goals in 51 games—an average of nearly one contribution per match.

In the Bundesliga, he scored 21 goals and finished second in the Golden Boot race, behind only Harry Kane (26). Over his last seven games, he contributed to 11 goals (9 goals and 2 assists)—a 1.5 average per match.

With Dortmund’s aggressive attacking style, Guirassy is expected to be heavily involved in the final third, and given his current form, it’s hard to imagine he won’t be part of a goal.

Facing Borussia Dortmund’s offensive approach, Fluminense may rely on counter-attacks, and Jhon Arias should be a key piece in this strategy. The Colombian is essential to Renato Portaluppi’s system and is the outfield player with the most minutes played this season.

Arias has 46 goals and 54 assists in 223 matches for Flu. His game is based on speed and dribbling, placing him among the top dribblers in the Club World Cup: 66 successful dribbles in 2025, alongside the likes of Vini Jr., Mbappé, and Désiré Doué.

This profile makes him a frequent target for fouls: Arias was fouled two or more times in each of the last five Brasileirão games. He ranks as the 2nd most fouled player in the competition, with an average of 2.9 per game.

If Fluminense had faced Borussia Dortmund about three months ago, when the German side was still inconsistent and mid-table in the Bundesliga, they might have had more of a chance. However, under Croatian coach Niko Kovač, Dortmund went on an impressive run in the final stretch of the season with six straight wins.

They secured qualification for the next Champions League and are expected to take the Club World Cup seriously, as it's their last opportunity for silverware this season. During this resurgence, they defeated strong opponents like Bayer Leverkusen (3–2) and Barcelona (3–1) in the Champions League quarter-finals—evidence of a team in top form. With standout players like Serhou Guirassy—Bundesliga’s second top scorer—Dortmund combines attacking quality and confidence to start with a win.

Fluminense, meanwhile, sits 6th in the Brasileirão and has been competitive domestically. However, they’ve struggled against teams with more structured attacks, as seen in their losses to Atlético-MG (3–2) and Botafogo (2–0) away from home. The challenge will be even tougher against a dominant Borussia Dortmund side, and the Brazilian team will likely struggle to hold off the Germans.

Borussia Dortmund games are often full of goals. Over the season, the team scored 106 goals in 50 matches (2.1 average) and conceded 72 (1.4 average), frequently surpassing the 2.5 goal line.

They’ve had 10 consecutive matches with over 2.5 goals. Dortmund attacks relentlessly but also leaves gaps at the back. They finished with the 3rd-best offense in the Bundesliga (69 goals) and conceded 50, reinforcing their tendency for open, high-scoring games.

The attacking standout is Serhou Guirassy, who scored 34 goals in 45 matches this season—nearly triple that of Karim Adeyemi, the team’s second top scorer.

Fluminense, although less aggressive offensively, can also pose a threat. They hold the 4th-best attack in the Brasileirão, with 14 goals in 11 games. Kevin Serna leads their domestic scoring with three goals, while Germán Cano, with 14 goals this season, is expected to start on the bench following injury.
