Gumbo is missing talismanic striker Knowledge Musona, midfielder Tinashe Nengomasha and captain Tapuwa Kapini but said this was not going to keep his side from winning.
He said he has seen the drive by the fringe players in training and is convinced that their firepower will prove to be enough to beat the Black Antelopes.
Gumbo said the upcoming players were motivated by the fact that the game would provide them with a chance to impress the coaches and the nation at large and thereby command regular jerseys in the Warriors set up.
In a 4:4:2 formation with Ariel Sibanda in goal, Gumbo is likely to have Vusa Nyoni, Noel Kaseke, Esrom Nyandoro and Carlington Nyadombo in defence.
With Nengomasha unavailable, the midfield is likely to present Gumbo with a problem.
He is loaded with playmakers like Quincy Antipas, Denver Mukamba, Khama Billiart, and Archieford Gutu, but no midfield anchorman.
Forceful Orlando Pirates striker, Takesure Chinyama, will surely have a run upfront with the support of either Nelson Mazivisa or Rodwell Chinyengetere.
It has been a torrid week for Gumbo, Ndlovu and David Mandigora in which they have been telling their players to go forward and multiply the goals.
Today at Rufaro Stadium, the coaches will know whether their gospel of fast attacking soccer sunk into their players’ heads.
The Warriors need a goal harvest at home ahead of the return leg in Luanda in October to assure themselves a chance of qualifying for the Nations Cup finals in South Africa in January next year.
