A solitary first-half goal from Daniel Svensson secured a 1-0 victory for Borussia Dortmund against Ulsan HD on Wednesday, allowing the Germans to advance to the last 16 of the Club World Cup.
Following their 4-3 defeat of Mamelodi Sundowns on Saturday, Dortmunds second consecutive win by a single goal ensured they topped Group F.
Fluminense qualified for the last 16 in second place after holding Sundowns to a scoreless draw in Miami.
Dortmunds coach, Niko Kovac, has often said the challenges presented by the intense heat in June in the United States, and this match was yet another played in extremely hot mid-afternoon conditions. Despite the heat, Kovac only adjusted his starting lineup, with Karim Adeyemi and Julian Ryerson coming in, while Jobe Bellingham retained his position in the squad.
The Bundesliga powerhouse could have won by a larger margin on another sweltering day in Cincinnati, but Serhou Guirassy was thwarted by a solid save from Jo Hyeon-woo in the 27th minute.
