Lebese is yet to feature this season, as he remains a peripheral figure at Chloorkop following his signing in August 2017 from Kaizer Chiefs.
Kapeluschnik, whose client is contracted to Sundowns until June 2020, says they are in talks with the Brazilians about the 29-year-old's situation in Tshwane.
"With Lebese ... uhh, we are talking to the club," Kapeluschnik tells KickOff.com.
"We are talking to Sundowns to see if they are prepared to let him get some game-time and they've been quite positive. So we just have to kind of take our agency approach and see what happens, but we are speaking to them. He is frustrated because he is not playing. We've told them that and they are open to the idea of him going to get some game-time."
Asked if there are any teams that have showed an interest in Lebese, Kapeluschnik says: "Well, we are not at that stage yet. It's November and the window opens in January. The guy is frustrated and they understand that and they are open to us ... but we haven't started looking."
