Sundowns tonight host AS Togo-Port in Tshwane needing to avenge last week's 1-0 defeat to the Togolese outfit to keep alive their hopes of advancing to the quarter-finals of the event.
The Brazilians will hope to turn their campaign around on home soil, having notably failed to win in six previous visits to West Africa over the years.
Downs are currently bottom of Group C with two points from three games - a point behind Togo-Port, and three shy of defending champions Wydad Casablanca and Horoya with three matches left.
Kekana, who had a poor game in Lome and was taken off early into the second half, is adamant Pitso Mosimane's side are still very much alive in the continental showpiece, which they won in 2016.
"No, no, not really,” responded Kekana when asked if it’s over for them in the competition this season.
“We still have nine points to play for and I’ve seen Sundowns play very well under pressure. I’ve seen Sundowns going to the second round.
“I think we should just be calm in front of goals. With the many chances we create, I think if we can take two out of those chances I think we are bound to win the match.
“We didn’t feel their resistance and I’ve seen Sundowns losing to teams with lesser resistance. One game that comes to mind was when we lost against Polokwane City [2-1 at Loftus Versveld Stadium in August]. Today it’s still hurting because the match was too easy for us, but we still ended up losing the match.
“To experience the same feeling against Togo-Port, it was sad for me and I didn’t take that loss very kindly.”
Meanwhile, Downs supporters wearing the club’s regalia will gain free entrance at Lucas Moripe Stadium this evening. Kick-off is at 21h00.
