Da Gama recently joined Black Lions, who bought the top-tier status of VTM FC and are hoping to tap into the experience of the South African tactician as they aim higher.
Now, Cossa, who was set to face stiff competition from Aden McCarthy, Rushwin Dortley, Bradley Cross and Given Msimango at Chiefs, is part of the project spearheaded by Da Gama in Botswana.
This could be a massive chance for the Amakhosi defender to develop and raise his profile, given that Da Gama has indeed worked with players who have gone on to establish themselves.
Da Gama worked with Shalulile at Highlands Park before the Namibian signed for Mamelodi Sundowns.
