The Brazilians, who are placed fifth on the league table, are eight points behind log leaders Cape Town City, but Sundowns have four games in hand.
"We haven't won a single match in our last three games (in all competitions) and that's one thing that needs to change. We need to start winning (again). We still have a realistic chance of defending our league title this season with these 12 games remaining," Kekana told IOL.
"All we need to do is to start collecting those three points in these remaining matches we still have to play, that's all," Kekana said.
The Bafana Bafana international is known for always having a powerful shot up his sleeve. He is best remembered for his goal for Bafana Bafana against Cameroon last year that earned him Fifa Puskas award nomination.
"I always had a good shot ever since I was a kid," he said.
"I remember when I started out at Black Leopards back in 2006, I hit Christopher Netshidzivhe with a powerful shot on the face. We were playing in a Nedbank Cup match against AmaZulu. It wasn't intentional," Kekana chuckled.
"I've noticed that no one in this current generation of players in the PSL is able to do what I do with the ball," he continued.
"They don't even attempt it. The accuracy of the shot is something that I always work on everyday in training to ensure that I never miss a shot whenever I'm presented with a chance to do so," Kekana streesd.
The African champions will face Bloemfontein Celtic in a PSL game at the Loftus Versfeld Stadium on Wednesday.
