Brendan Venter has tipped South Africa assistant coach Johann van Graan to take over as head coach of the Bulls after the Rugby World Cup.
Frans Ludeke's departure has left a vacancy for the top job in Pretoria after he parted ways with the Bulls following the end of the Super Rugby season.
Venter, who was speaking at the 20th anniversary of South Africa's World Cup triumph on Wednesday, added that a combination of Van Graan working with Victor Matfield and Fourie du Preez could be a success.
"Van Graan is a really good coach, I think he will take over and Fourie du Preez and Victor will help him, it will be as simple as that," Venter told Sport24.
"Victor and Fourie will coach with Johan, and they are talented people and if they do things well they can be successful."
The departures of Ludeke, Allister Coetzee at the Stormers and Naka Drotske from the Cheetahs have left three big jobs to fill in Super Rugby, with Venter concerned about the lack of potential new coaches coming through the ranks in South Africa.
"All of them were in the jobs a long time, they needed change and the coaches knew it as well, and change is as good as a holiday," added Venter.
"My question is who is going to coach us? I am looking and going whoa, there is not much out there. There are just not that many good quality coaches out there, the most of them are in a job.
"How do you find a coach with a good pedigree, with not too much baggage, without a job?"
