Leonid Slutsky accepted the blame for Hull's 5-0 thrashing by Derby at Pride Park.
Hull were four down at half-time and the Russian manager described the result as the worst of his career.
Hull have not won an away League game since the start of last season but they could not have envisaged how bad this defeat would get, even after Matej Vydra drove a 20-yard free-kick past the defensive wall in the 15th minute.
It might have been different if Sebastian Larsson had converted a penalty when Tom Lawrence hauled over Ola Aina in the 27th minute but he blazed high over the bar and the rest of the game turned into a rout.
