Kekana had several rasping attempts from range saved by Celtic goalkeeper Patrick Tignyemb, including a dipping direct free-kick the Cameroonian dived to keep out in the first half.
It is an aspect of his game the Bafana Bafana international looking to hone even more to become a bigger threat in front of goal.
“I’ve been working on this shooting throughout the week and I knew with Tignyemb you have to be of a very sober mind to test him,” Kekana said on SuperSport TV.
“I tried on so many occasions to unsettle him early in the game, but he was very strong on that and he made good saves, but I’m happy with the three points.
“It was a very tough match to be honest, it’s the second round of the season where everybody counts for everything so we know it’s not going to be easy but we have to grind out the results and that’s what we did tonight,”
“They are a very good team and we should give credit to them, they took the game to us. But I must give the boys a job well done because it wasn’t easy but we managed to come away with three points and we’re happy with that.”
Sundowns’ next assignment is away against Orlando Pirates on Saturday.
