The A-League Pre-Season Cup final will see Mariner Tony Vidmar up against his brother Aurelio, Adelaide's assistant coach.
But one of the main interests in the pre-season cup final between Central Coast and Adelaide at Gosford will be on the benches.
It will be the first time since Tony Vidmar's return to Australian club football as the Mariners marquee signing the Socceroos defender has come up against older brother Aurelio, the Reds assistant coach.
"It'll be interesting," said former international Aurelio, who has been in charge of the bulk of Adelaide's preparation with head coach John Kosmina away in Sydney this week with the national team.
"It's nice to have a bit of family on the other side of the table. We've come across each other a couple of times overseas, although we never actually played against each other."
"One time I got a couple of stitches in my head and came off as he was coming on, and one time in Holland we were both on the bench for opposing clubs."
After getting through 50 minutes in his club debut last week - his first game in six months - Tony Vidmar is again expected to start on the bench for the Mariners while he continues his comeback from the heart condition which ruled him out of the World Cup.
Central Coast, playing its fourth final in 15 months, still has several key players nursing injuries, including attackers Nick Mrdja (knee, 4 weeks) and Tom Pondeljak (groin, 2 weeks).
Adelaide will also be understrength with Fernando Rech and Bobby Petta unavailable.
Enigmatic forward Shengqing Qu, however, could be a late inclusion if his clearance from the Chinese football federation arrives before kick-off. As of late Friday, Football Federation Australia were still awaiting the clearance.
The game at Central Coast Stadium is a re-match of last season's preliminary final - won 1-0 by the Central Coast.
Adelaide beat Sydney FC 2-1 in last weekend's semi-final to book its berth, while the Mariners beat Newcastle 2-1 in extra time to maintain their remarkable record of featuring in all four competition finals since the A-League's inception.
"You've got to pay them a lot of respect because it's never easy to play in any competition and front up for every final possible," said Adelaide's Aurelio Vidmar.
"They've got to be doing something right, and it amazes me how many injuries they seem to get and still put out a competitive side. We've got to be smart about how we play and match their intensity."
"On our day we can beat anyone. If we're fully concentrated I don't have any doubt we can win this cup final."
