The Reds haven't played at Adelaide Oval since the Round Two 1-1 draw with Melbourne Victory.
Adelaide lost both of their league encounters at home against Brisbane Roar this season, 1-0 and 3-2.
However the Reds triumphed 2-0 when the pair clashed at Coopers Stadium in the FFA Cup back in September.
Phoenix defeated City in their only encounter this season at Westpac Stadium 5-1 back in November.
The two clubs played out 0-0 draws at Lower Hutt and Melbourne's AAMI Park, a fortnight ago, also this season.
