In the winter transfer window, newly appointed manager Josep Gombau was quick to add Spanish flavour into the squad. He brought in fellow Spaniards Sergio Cirio and Isaías. He also added other players including Tarek Elrich and Steven Lustica, Michael Zullo for a season long loan and Brent McGrath as a four-week injury replacement player. Awer Mabil and Jordan Elsey were also promoted from the youth system, each rewarded with two-year contracts. The club also let four contracts expire; those of Iain Ramsay, Tomi Juric, Fabian Barbiero and Evan Kostopoulos. Iain Fyfe and Zenon Caravella both had their contracts cut short and terminated. Sergio van Dijk was transferred to Persib Bandung and Dario Vidošić to FC Sion for a reported $700,000 transfer fee.
The Reds had a shaky start to their season under new manager Gombau. They had only a single win in their first nine games for the season and early calls started for the club to show the door to the new man in charge. Gombau quickly changed the club's fortunes, getting his second win in round 10 against the Central Coast Mariners, with a 4–0 result. The team continued this form to finish sixth on the table after the 27 home-and-away games, which let them into the finals by two points. Adelaide's season was ended by Central Coast in the elimination final, losing 1–0.
The Reds' highest attendance in the 2013–14 season was 16,504 in the round 2 clash with Melbourne Victory at Hindmarsh Stadium which ended in a 2–2 draw.
