Kick-off is at 19h30, with Stars looking to bounce back from a 1-0 loss at Black Leopards in their play-offs opener.
Jomo Sono's Cosmos drew 2-2 at home with Lidoda Duvha in their first play-offs outing.
“Cosmos has been in the PSL for a long time, we know they are not going to change," says Tshabangu.
“We know Jomo how he plays, we know what kind of football they play. They have not changed, they have been playing the same football they have been playing.
“Playing in the first match it was difficult because before we didn't know where we were standing and the preparations were late.
“We even arrived down there around 11pm. We were tired and we were playing at 3pm. Even a day before, we were training hard thinking maybe we are not going to play on Wednesday and they will change the game to Friday.
“We were tired but that's not an excuse, we have to work and this is our job.”
Tshabangu is urging his team-mates to make the most of the second chance they have been offered to remain in the Premiership.
Dikwena were initially relegated but were given a lifeline when SAFA docked seven points from Ajax Cape Town for fielding an ineligible player in Tendai Ndoro. The Urban Warriors were then automatically relegated with Dikwena elevated to the play-offs spot.
“The way I look at things we will win. We have a good squad and we are motivated to win because you saw how things happened where we were given a second chance and we have to use it.”
He adds: “We still have a chance, we still have three games to go. Losing one game doesn’t mean we are not going to make it.
“We will make it. We have to be focused and have hope. We know we want to do it. We are playing NFD teams and we have to fight, there is no other way. We will do it no matter what.”
