The 2009-10 campaign delivered a triumphant return to the professional ranks for Fortuna Düsseldorf as Die Flingeraner, newly promoted after a decade away, surged to a spectacular 4th-place finish in the 2. Bundesliga, narrowly missing the promotion play-off spot. Spearheading the charge was the clinical loan forward Martin Harnik, whose 13 crucial goals made him the club's top scorer in a memorable comeback season that re-established their place in German football's second tier.
