Derby boss Paul Jewell branded his players as "not good enough" after their final day thrashing by relegated Reading.
Jewell said: "I think it sums up the season, the players are not good enough for the club.
"I'm the manager so I'm part of that group but I know I've got the desire, the fire in my belly and the passion to have a good go at turning it around.
"Too many of those players haven't, it's as simple as that."
County have now become only the second team in the history of English football to win just once in an entire league season - the first was Loughborough College 108 seasons ago.
They can also add the unwanted record of lowest goals tally to earliest relegation and smallest points total in Premier League history.
A furious Jewell added: "You can't believe it really that a team that's fighting for their lives, who are nervous and edgy would come and dominate a game here like they have.
"But they have, it's a complete embarrassment."
