According to football411.com website, Amakhosi are three points clear at the summit almost at the halfway stage of the season.
'Yeye', as his affectionately known, told Football411 that the Glamour Boys are far from comfortable with their performance thus far.
Letsholonyane explained: "Satisfied no, but I'm happy with the results we have got so far.
"I can't be satisfied because we believe as a team that there is still room for improvement. There are still areas in our game that must improve so I can't say I'm satisfied.
"If you check all our games, we haven't been consistent in terms of the way we play throughout the 90 minutes. We switch on and off, so that worries the coach (Stuart Baxter)."
The Bafana Bafana international added that the issue has been addressed in a meeting between the players and the technical team and he hopes the message was loud and clear.
"It is something that we have spoken about as a team and the period we identified is the way we play after 70 minutes of a game," the 30-year-old added.
"We tend to relax. Obviously there are two teams playing against each other in the field so there would be moments when the other team is good so we would chase after the game at some point, which is normal.
"But as a team, we feel we allow teams too much time to play and that can be dangerous. I hope we have managed to sort this out."
