Serhou Yadaly Guirassy (born 12 March 1996) is a Guinean professional footballer who plays as a striker for club Borussia Dortmund. Born in France, he plays for the Guinea national team.
Guirassy began his career at Stade Lavallois, before playing for Lille OSC, 1. FC Köln, Amiens SC and Rennes. He later joined VfB Stuttgart, where he set a club record by scoring 28 goals in the 2023–24 season. In 2024, he moved to Borussia Dortmund, where he became their top scorer in a single Champions League campaign with 13 goals in 2024–25.
In his second season, he scored his first goal in a 2–1 away defeat against Bayer Levekusen on 28 October 2017. Five days later, he scored his first goal in the Europa League in a 5–2 victory over BATE Borisov. Later that month, he scored the only goal in a 1–0 win against Arsenal in the same tournament. Eventually, 1. FC Köln finished last in the league to be relegated, with Guirassy being their top scorer in all competitions.
On 15 February 2020, he scored a brace in a 4–4 draw against Paris Saint-Germain, with his second goal equalized the match in the stoppage time. However, Amiens were relegated while being at 19th position, when the league was suspended prematurely following the outbreak of COVID-19 in France.
In the 2023–24 season, Guirassy scored ten goals in the first five matches, including his first Bundesliga hat-trick which came against Mainz, to equal a previous record set by Robert Lewandowski in 2020–21. He also set the Bundesliga record for most goals by a player in the first seven matches of a season by scoring a hat-trick within 15 minutes in a 3–1 win against VfL Wolfsburg. This set the record at 13 goals, overtaking Lewandowski's record of 11 in both 2019–20 and 2020–21. After scoring his 14th goal of the season in an away match against Union Berlin, he was substituted after 30 minutes of play due to a hamstring injury. He later missed two league matches, before he managed to score a penalty to secure a 2–1 victory over Borussia Dortmund, and to reach 15 goals in his first nine matches of the season.
On 13 April 2024, he scored his 25th Bundesliga goal in a 3–0 victory over Eintracht Frankfurt, breaking the record of most goals by a Stuttgart player in a single campaign set by Mario Gómez in the 2008–09 season. A few days later, he was named Player of the Month for March, achieving the prize for the second time in the season after September 2023. On the final matchday of the 2023–24 season, he netted a brace in a 4–0 win over Borussia Mönchengladbach, finishing the season with 28 goals in 28 matches, only behind Harry Kane. Additionally, he scored the opening goal for the 12th time that season during the match, tying a Bundesliga record set by Gerd Müller in 1969–70, Ailton in 2003–04 and Stefan Kießling in 2012–13.
On 15 April, he netted his first Champions League hat-trick in a 3–1 win over FC Barcelona – against whom he also scored a brace months prior – during the quarter-finals of the competition, becoming Africa's and Dortmund's all-time top goalscorer in a single campaign with 13 goals. With his hat-trick, he also became one of only four players next to Lewandowski, Marco Reus and Karim Adeyemi to ever score a hat-trick for Dortmund in the competition. Guirassy ended his first Champions League season with Dortmund with fourteen matches played, thirteen goals scored and four assists provided, securing the top scorer spot in the competition alongside Raphinha. Hence, he became the second African player to achieve this feat, only after George Weah in 1994–95. In the 2025 FIFA Club World Cup, he netted a brace in a 2–1 victory over Monterrey, qualifying his club to the quarter-finals.
In December 2023, he was named in the Guinean squad for the 2023 Africa Cup of Nations in Ivory Coast.
With six goals, Guirassy was the second top scorer during qualification for the 2025 Africa Cup of Nations, only behind Morocco's Brahim Díaz. This was not enough to progress, however, as Guinea missed out on the finals for the first time since 2017.
