With Fortuna chasing their fourth shutout in as many Bundesliga games, coach Norbert Meier unsurprisingly kept faith with the same starting line-up that held VfB Stuttgart to a goalless draw on Matchday 3.
The home side's trademark dogged resilience was on show from the get-go, and when SC Freiburg did manage to work some space on the flank, Fortuna keeper Fabian Giefer was equal to the task.
Fortuna carried the greater attacking threat for much of the first half, with Freiburg lacking the necessary invention to unlock the Fortuna door from open play, and Andriy Voronin passing up a decent opportunity to play in Danny Schahin following a promising counter for the hosts.
Four games and counting
Looking to become the first side to breach the Düsseldorf back four this season, the visitors started the second half pressing high up the pitch. Meier's charges were always a threat on the counter, though, as Schahin almost got on the end of Robbie Kruse's inch-perfect delivery after 52 minutes.
Both coaches signalled their intent with a string of attack-minded changes, and it was the introduction of Rafael that so nearly won it for the home side, with the substitute desperately unlucky to see his close-range effort come back off the crossbar deep into added time.
