Pirates will visit Abafana Bes'thende tomorrow at Durban's Moses Mabhida Stadium in the last league match of the season.
Rakhale's side still have a mathematical chance of finishing inside the top half of the table but need to hope that Ajax Cape Town, in eighth and three points above them, lose to Baroka FC.
Platinum Stars are also in contention and Pirates require Dikwena to lose or draw in their final game against SuperSport United.
Apart from needing those two results to go their way, the Soweto giants cannot afford to simply beat Arrows - they need a significant margin of victory as the Urban Warriors have a superior goal difference.
The most recent encounter between the two sides, a Nedbank Cup semi-final contested only last weekend, was narrowly edged by Pirates who won 1-0.
The Sea Robbers have scored more than two goals in a league match only once this season, granted it was against Arrows at the start of the campaign.
Their biggest margin of victory has been only two goals, achieved once this season and in the event Ajax lose by a single goal Pirates would require at least a four goal margin of victory in their game.
"It's huge one. We'll just give our best and try to win with a big margin of score and then maybe we'll be in the better position in terms of the log," said Rakhale, named Man of the Match against Arrows on Sunday.
"But anything is possible. We just want to go there and win the game and then come 90 minutes we'll see where we are."
The 27-year-old returned from a long term injury last month, appearing in his side's Nedbank Cup quarter-final clash against Bloemfontein Celtic and making a significant impact as he delivered a pin-point cross which was headed in by Thamsanqa Gabuza at Orlando stadium.
Rakhale, who hasn't scored a league goal this season, says it was hard being on the sidelines and, now that he's back, he wants to give his best on the field pf play.
"It's great feeling to be back," Rakhale added. "It was frustrating that I didn't play for three months. And now that I'm back, I'm just giving my best shot so that I can stay and remain in the starting eleven."
