The Belgian mentor was brought into the Chilli Boys as a replacement for Musa Nyatama, who lasted just one game in charge after he started the season as number two to sacked Sinethemba Badela.
Morgan Mammila assisted Eymael for the 3-0 defeat to Orlando Pirates last week but the new Chippa boss has since opted for Mosala, with Mammila now set to resume his duties as technical director.
Mosala and Eymael previously worked together at Polokwane City and Free State Stars and are now charged with propelling the Chilli Boys up the Betway Premiership standings.
Eymael has also brough Walid Ben Othman as the Chill Boys' new goalkeeper coach.
Speaking to FARPost, the head coach said: “You know, Sly worked with me at Polokwane City and at Free State Stars. So it's not a big surprise. Morgan [Mammila] is my friend, but it was like that. It was a decision of the big boss.
"Yeah, we brought a new goalkeeper coach who was working with me in Libya, Tunisia and in DR Congo. You know that we qualified [FC Saint-Eloi] Lupopo for the CAF Champions League. We had the most clean sheets in the league and beat TP Mazembe twice.
"So it's also very important to give Stanley [Nwabali] some confidence because when the spine is doing very well, the rest we can build around that. The most important thing is to stabilise the spine, and then after that we can adjust all other things.
"But I think everybody is bringing a bit of confidence to the player and their view and technical abilities to the players."
Chippa are currently in 14th place on the league standings with four points from six games and are next in action against Polokwane on Sunday.
