Competition in central midfield in Bafana is stiff, making Mthethwa's path into the national team a difficult one.
The likes of Thalente Mbatha, Teboho Mokoena, Masindi Nemtajela and Bathusi Aubaas are all on top of their game, strengthening their grip on their spots in the national team.
That gives Broos little reason to tamper with his preferred central midfield structure, thereby shutting out Mthethwa.
Adding to more competition in this role are players like Orlando Pirates' Sihle Nduli and Sekhukhune United’s Siphesihle Mkhize, who are also pushing hard for Bafana recognition.
This depth of quality makes it increasingly difficult for Mthethwa to stake a claim for a place in the national side.
His challenge could be further compounded by Broos’ apparent lack of faith in Chiefs players.
