Ulsan's hopes of progressing to the next phase have diminished with their loss to the South African team Mamelodi.

This format is played in three matches during the group stage, and they now face much more challenging obstacles in Fluminense and Dortmund.

Fluminense, on the other hand, has demonstrated defensive proficiency against one of the most lethal attacking teams in Europe's top five leagues, Dortmund.

They kept a clean sheet thanks to their experienced captain, Thiago Silva, who played an excellent master defensive game.
