Brys has had a strained relationship with Cameroon Football Federation (FECAFOOT) president Samuel Eto'o since he took the position in April 2024, although his role is financed by the Ministry of Sports and Physical Education.
The coach stated in a letter to the ministry, which was reviewed by Reuters, that he has made the "decision to unilaterally terminate the said contract for cause, due to the non-payment of my remuneration and that of my staff for more than 60 days."
FECAFOOT released a statement on Wednesday acknowledging the resignation and stating they would "implement a coordinated response to mitigate the impact of this vacancy at the head of the national team's technical staff."
Cameroon has been placed in a group with the defending champions Ivory Coast, Gabon and Mozambique for the AFCON finals, which will commence in December.
Currently, they are in second place in their qualifying pool for next year's World Cup in the United States, Mexico, and Canada, just one point behind Cape Verde with four rounds left. Only the top team automatically qualifies for the finals. The qualification campaign will conclude in September and October.
