Mbatha joined Yanga three days ago, but he has not been officially introduced to the public and his job is not known as Yanga do not have the CEO post, which he was heading at Simba SC.
Hersi Said, an official at GSM Group that are Yanga's kit sponsors, said the club will create a post which will be headed by the South African, saying they consider naming him the chief advisor of the club.
He said Mbatha has vast experience in football management and the club believes he will be of great help to its aim of transformation to become a commercial entity and also maintain the relationship which Yanga has with Spain's La Liga.
Said also said Mbatha will be influential in professional football administration of the club and recruiting of players for the club.
"Mbatha has vast experience in running football, we are of the view that his experience and knowledge will help Yanga in many ways, we will create a position which will be suitable for him to execute his duties," he said.
After Mbatha was seen signing for Yanga, there have been many views as some sections of domestic soccer lovers are of the view that Yanga should amend their statutes to create the CEO position and outline the post's responsibilities.
They argued that by becoming an advisor to the club management, his post is bound to overlap between the functions of Secretary General and club president, a situation which will not be healthy for the club.
While at Simba, some of Mbatha's primary goals were internal restructuring of the club, transformation of football, promotion of Simba brand and development of new business.
