The attacking midfielder spent nine years with Chiefs before leaving the Naturena-based side for Sundowns at the beginning of the current season.
Sundowns are now scheduled to host Chiefs in a highly anticipated PSL match at the Loftus Versfeld Stadium.
“Yes,” said Lebese on The Citizen, when asked if he would celebrate a goal on Tuesday.
“I respect Kaizer Chiefs, they are a big brand, they taught me everything," he added.
"But at the end of the day it is about entertainment, and about where I am right now. I am in a happy place, so if I score, why not?”
The 28-year-old disclosed that he has been ignoring the phone calls of his former teammates at Chiefs in the build up to this game.
“I have been avoiding talking to them for the past two weeks, that is how crucial this game is. We will definitely speak after the match," he concluded.
Lebese has featured in three league games for Sundowns this season - netting once in the process.
