The Chilli Boys have gone eight matches without a victory in the league, with their last result being a 2-0 loss to log leaders Bidvest Wits.
In the first round in Bloemfontein, Celtic beat Chippa 2-0 thanks to goals from Tebogo Potsane and Tshegofatso Mabaso, but Masutha is confident of gaining revenge.
"Ja, I believe we are ready," Masutha tells KickOff.com.
"We are ready. We know the importance of the match, and a win will give us the confidence that we have been lacking. It will also help us going into the next games. It's important to win and I have all the confidence that here we will definitely get the three points. The break helped us a lot because it made us get used to each other better, because if you remember I just came on a few days before ... I think in two weeks we played three games, so there was not enough time for training. It was just more about motivating the guys and trying to free them to play without pressure. But now they know exactly what we need. The time also hasn't been that much but I believe we are ready. The understanding between what we need and what the players are supposed to do is much, much better now.
"Very solid team (Celtic), very strong team, well organised and they also have experience you know. They have dangerous players, if left unchecked they can cause serious damage. But you know we are not worried more about the opponent, we are worried about what we can do and what we have to do. But again they are a very, very organised team. They don't give much away and you know they can sit back, defend ... but you know their breaks also, quick breaks which has worked for them very well this season. So we are prepared to be honest. I think a win will help us a great deal."
Chippa are second-from-bottom on the table with 12 points from 15 games - nine points less than seventh-placed Phunya Sele Sele.
Cash-strapped Celtic will be steered by Lehlohonolo Seema and John Maduka following coach Steve Komphela's resignation in December.
