Borussia Dortmund may be without Serhou Guirassy for next week’s Bundesliga showdown with Bayern Munich after his thigh injury resurfaced while with Guinea.

Guirassy has scored four goals in five Bundesliga outings this campaign, with Dortmund taking 14 points from six matches to sit second in the table, four points behind Bayern.

The striker recently missed Dortmund’s meeting with Mainz due to a thigh problem, though he returned with a goal in a 4-1 Champions League triumph over Athletic Bilbao before playing 81 minutes in a 1-1 draw with RB Leipzig.

So far this calendar year, Guirassy has scored 32 goals in 39 games across all competitions, with only Kylian Mbappe (44 goals) and Harry Kane (39) netting more often among all players from Europe’s top five leagues.

No player has had chances with a greater cumulative expected goals (xG) value than Guirassy (34.82) in that same span, while he has a shot conversion rate of 25% and has averaged a goal every 102 minutes.

However, Guirassy was an unused substitute as Guinea drew 1-1 with Mozambique in a World Cup qualifier on Thursday, and ahead of Tuesday’s match against Botswana, he has returned to Germany.

“With the permission of the technical staff, striker Serhou Guirassy has left the national gathering to rejoin his club,” the Guinean Football Federation said in a statement.

“Diminished physically, Guirassy held on out of love for Guinea and out of respect for the technical staff, to come to the regrouping of the national team in Mozambique.

“The player had also expressed to the staff his wish to support his team-mates through his presence, if only for one match, before returning to the club.

“The Guinean Football Federation, the staff, his team-mates and the sporting public wish Guirassy a speedy recovery and hope to see him again as soon as possible.”

Guirassy recently scored in eight successive Bundesliga games spanning the 2024-25 and 2025-26 seasons, but he went three league matches without a goal before the international break.
