Pinchbeck United boss 'absolutely embarrassed' after three red cards in 5-1 defeat at Boston Town
Ian Dunn admitted eight-man Pinchbeck United's derby defeat was "the lowest point" since taking over as manager.
The Knights were thrashed 5-1 at his former club Boston Town on Tuesday night.
Lee Beeson and Alex Beck hit doubles against the club which they left during the summer.
Niall Hylton, Tony Edwards and Nathan Kelly were all sent off in a 15-minute spell during the second half.
Dunn felt "absolutely embarrassed" after the result which leaves Pinchbeck on five points from nine games in the uhlsport United Counties League Premier Division so far this term.
The player-boss said: "I can't argue with the red cards.
"I don't understand why they happened when we had potentially got ourselves back into the game.
"We were on the front foot and we've thrown it away. The chance had gone.
"This is probably the lowest point since I've been at the club. I don't know where we go from here.
"Before the game, we spoke about stopping Beeson. Then we allowed him to put in four crosses in the first 15 minutes.
"At half-time, we needed to pick ourselves up because it didn't look like we wanted to be out there.
"In the first half, we were second to everything all over the pitch. We didn't put in a challenge, any tackles or a block. It was too easy.
"We came out for the second half and had a go at them to make it 3-1. It was a long shot to come back from giving away three stupid goals."
Pinchbeck have signed University of Lincoln students Kai Wilson, Callum Wilson and Ryan Evans.
The Knights are back in action at the Sir Halley Stewart Field on Saturday when they face Worcester City in the Buildbase FA Vase first round.
