Du Plessis was speaking on their return from a dismal Tour of India on Friday. He and the Proteas suffered a humiliating 3-0 loss to India in the Test series after having drawn their three-match T20 Series 1-all in September.
Du Plessis has lamented that a permanent structure needs to be appointed as soon as possible.
After being outplayed by India in all departments during the Test series as it wore on, Du Plessis says he believes that they need to get mentally stronger in order to compete at the highest level to get results.
The Proteas, who have had a handful of young players make their Test debuts during the tour of India, are going through a vicious rebuilding phase, but certainly have not embarrassed themselves in the subcontinent.
Du Plessis reiterates that there is still a long journey ahead of the young South Africans but their mission is to eventually return to the No.1 spot in the world one day.
The 35-year-old has also called on CSA to start incorporating more former Proteas players in their coaching structures to assist young players to grow their mental game as early as possible in their careers.
Du Plessis adds that the current Proteas side needs that kind of experience in the team right now.
