Ricardo Mannetti has resigned as Namibia coach just four days before the Warriors host Zambia in a 2016 CHAN qualifier.
Namibia hosts Zambia on Sunday in a CHAN qualifier first round, first leg match in Windhoek.
In a statement, the Namibia Football Association said Mannetti stepped down from the job on Thursday after talks over a new contract collapsed.
Mannetti quit less than a month after leading Namibia to their debut Cosafa Cup triumph in South Africa whose highlight saw them eliminated the then defending champions Zambia at the quarterfinal stage on post-match penalties.
“He did not accept what he was offered and decided to step down from the senior national team. It is a decision that has shocked us and we are disappointed by it but we have to respect it and move forward.” NFA general secretary Barry Rukoro said.
Rukoro said Manetti’s assistant and former Namibia and Mamelodi Sundowns goalkeeper Ronnie Kanalelo will take charge as interim coach.
The ex-Namibia defender has been coach since 2012.
His last match in charge was last Sunday in a 1-0 away loss to Niger in a 2017 Africa Cup Group K qualifier.

Lets bang them; Bajaila!
