Second-from-bottom Ajax will host Chiefs in their final league game of the campaign on May 12 at Cape Town Stadium, needing a win and hoping that SuperSport United or Polokwane City stumble in their respective home matches with Baroka and Chippa United.
Booysen is confident the Urban Warriors can defy their critics and beat Amakhosi, who recently parted ways with coach Steve Komphela after their Nedbank Cup semi-final loss to Free State Stars condemned them to a third straight season without silverware.
"It's a bit unfair on us but this just spurs us on to get the job done against Chiefs and prove our critics wrong," Booysen tells KickOff.com.
"We've been getting stronger and stronger and our overall game has improved, and this of course is down to the work of our passionate coach Muhsin Ertugral. The luck, especially in our away games, has eluded us.
"But we have the belief that we can overcome this together. The players are aware our fate is in our own hands now and it's time we deliver."
Booysen doubts Muhsin Ertugral's side will need to win the play-offs to avoid the fate of already-relegated Platinum Stars, who are desperately counting on the Tendai Ndoro eligibility saga to cast them a lifeline.
"Na, I don't think it's going that route," Booysen says. "You must remember Chiefs is also not in a very good space. Yes, they are coming off a win [2-0 victory over Maritzburg United] but they are trying to get settled after losing their coach.
"So, to me they are still very much beatable, especially here in our own backyard you know.
"We have shown how good we are at home and we are well prepared and fully focused on Chiefs. It's a pity we couldn't play the game in the Athlone Stadium as we are unbeaten there.
"The Baroka and SuperSport game will have to have a winner and this sort of swings things in our favour as well. That is why we have to do our job and get three points against Chiefs.
"That is our main priority and like I said our fate is in our own hands," concludes the 29-year-old former Mamelodi Sundowns and SuperSport centre-back.
