If Gold Coast beat Mariners then third is theirs to lose
The rescheduled match from December 19 takes place at Skilled Park which will be the Gold Coast's second last match of the regular season.
Three points will have them move ahead of current third-placed holders Adelaide United whilst also moving them to within two of the second-placed Mariners.
With either a double chance (second place finish) or a home final (third) the result of the last two matches, Bleiberg has urged his men to hit form heading into the playoffs.
"The calculation is very simple; third place is in our hands," said Bleiberg.
"If we can win our next two games we will finish at least third. We want to finish as high as possible and we will be going for it in both matches.
"It's also very important to go into the Finals Series with the right momentum so we have two good reasons to secure another win on Wednesday evening.
"Even teams who can't improve their position on the ladder will want to end the season on a high so they can take that form into the finals.
"It's very important because wins breed wins, and losses breed losses."
