In late 2015, Song was reportedly close to becoming the manager of the Chad national team but an agreement was never finalised. In February 2016, Song was appointed as manager of the Cameroon A' team, which is composed of players based in Cameroon. Following his hospitalisation for a brain aneurysm and subsequent recovery, Song resumed coaching duties in 2017, ahead of the qualification stage of the 2018 African Nations Championship. He led the team into the tournament, which saw Cameroon finish bottom of their group after two losses and a draw.
