Sundowns are currently second from bottom in the league standings with just one win all season.
But they face off against neighbours University of Pretoria in the last 16 of the Telkom Knockout on Tuesday and Modise insists a win will help the Brazilians turn the corner.
"There is nothing wrong at Sundowns," he told Football411. "The only thing to do is to start winning games. We know the pressure that we have, we have been saying this as players so we have the obligation to deliver. Hopefully we can do that in this game against AmaTuks.
"We will try to stay positive even though we are not getting positives results," he admitted. "But we have been playing well and the only problem is that we are just making a couple of mistakes.
"We know that against AmaTuks there has to be one winner and we will focus on that game for now," Modise asserted.
Turning his focus to the PSL, Modise is adamant that Sundowns, currently in 15th position after seven matches, can still win the league.
"We are not playing in England where once Manchester United are number one that's how it's going to end. In South Africa, we have seen teams before in top positions but when the league ends, it turns out different. So for us the race is still on," Modise added.
