According to dpa information, the player won’t be available due to gastrointestinal problems. Guirassy just returned to the squad after playing the Africa Cup on Nations with Guinea. The national team was eliminated in the quarter-finals on Friday. The forward has scored 16 goals in 19 games so far this season.
