Norwich City boss Alex Neil apologised to fans after their 5-0 thrashing at Brighton - the heaviest loss during his time at the Championship club.
The Canaries, relegated from the Premier League last term, were top on 15 October but have slipped to fourth after two defeats in three games.
"It was my worst defeat as a manager, a humiliating defeat," said the 35-year-old former Hamilton boss.
"The players need to try and play better it's as simple as that."
Against one of the teams expected to be their rivals for promotion, Norwich produced just two shots on target in a lacklustre display.
