Valencia sacked Carlos Corberán, the head coach of the football team. This decision in itself would not be particularly surprising in the world of sport, where coaching changes are frequent.
However, the word the article highlights as fundamental is not "sacked", but rather "entire". Valencia did not simply swap the coach.
The club sacked Carlos Corberán and the entire football structure. In other words, it was not just the coach who left, but the entire department responsible for the sporting area.
The article's title, "The coach is the fuse, never the circuit", indicates that normally coaches are the scapegoat when something goes wrong at a club. This time, however, the club chose to replace not just the fuse, but the entire circuit.
