Plumber
In South African football, the term "plumber" is a derogatory slang used to describe a coach, often a foreign one, perceived as underperforming or lacking the intellectual or tactical acumen to succeed in the sport. It implies a coach is more suited to a trade like plumbing than managing a football team.
I see Orlando Pirates just hired a plumber to replace Riveiro.
