Norwich City boss Chris Hughton admits FA Cup defeat to Luton Town was among the lowest points of his career.
The Conference club stunned the Canaries at Carrow Road.
Hughton admitted: "It's right up there, yes.
"Our form has taken a real dip and we're in a difficult place at the moment.
"The scoreline is a reflection of that. As manager I take full responsibility - it's an awful day for us.
"I had a team out there who were good enough to win but I don't want to take anything away from Luton."
