Tlhopie is set to succeed his father Patrice Motsepe as the new man in charge of The Brazilians as the mining magnate succeeds Ahmad Ahmad in leading African football.
Motsepe will be officially elected this week after Jacques Anouma, Augustin Senghor and Ahmed Yahya withdrew from the race for the biggest football position on the continent.
The billionaire announced in Sandton recently that his first-born child Tlhopie will take over as the new president of the club in the event that he is elected CAF president.
Dr Rejoice Simelane, who is currently a director at Chloorkop and on the PSL's Executive Committee, is set to serve as the club's vice president.
"If I get elected CAF president, I will step aside and my first-born [Tlhopie] will replace me as the club president," Motsepe was quoted in delivering his manifesto in Johannesburg last week.
"My heart will always be with Sundowns. The CAF rules say that a president cannot be associated with the club. I will become an ordinary Sundowns fan. My son, I am throwing you into the deep end."
Although Tlhopie remains media-shy, he has always been a regular figure with his other two brothers Kgosi and Kabelo showing support during Sundowns home games in Tshwane.
Those close to Motsepe Jnr have described him as a very humble person.
He is also regarded as a budding young businessman who is ready to follow in the footsteps of his father and is listed among the directors at a solar energy company, ePower Holdings.
