He said: "My son will make a sober decision. Be patient, he will make a decision in the coming days.
"I have talked to him and, while I am not going to interfere in any way with his decision about his future, it is my place to advise him.
"But I make it a point never to interfere with my sons' professional affairs. They are mature enough to make sensible decisions.
"All I do is to give them fatherly advice to ensure they are not carried away by their status.
"My sons have never let me down. Their discipline has been great. I ensured they grew up the way I taught them. I am a disciplinarian, and self-control was instilled in them."
