Northampton boss Gary Johnson was left bitterly disappointed after his side made it 15 games without a victory following a 4-2 defeat against Bury.
Ryan Lowe, Nicky Ajose and Damien Mozika eased Bury into a 3-0 half time lead. Ajose grabbed his second to make it 4-0 before Shaun Harrad scored two consolations for the struggling Cobblers.
"We're so disappointed with our first-half performance, we were very poor and at times it was embarrassing," said Johnson.
"Having to change our goalkeeper didn't help because it meant I had to use a substitute so early in the game and if I could have used 10 substitutes at half-time I would have done!
"The players are making the wrong decisions at crucial times and that's the only reason I can give for our first-half display. We are allowing opponents to get into us too easily but at least we didn't capitulate in the second half.
"I could walk out but that wouldn't help the situation. You sometimes question yourself in these situations but the players have got to believe they can stay up and we've all got to do everything we can to make sure we stay clear of the relegation zone. The only way to get through it is to work even harder."
Bury caretaker boss Richie Barker was full of praise for his free-scoring team, saying: "That was an excellent performance, but we made things difficult for ourselves by conceding goals in the second half and it could have ended up 8-5!
"It would have been nice to keep a clean sheet but we played well as a team although not always as individuals. We could have made it easier for ourselves in the end but our goal difference could prove crucial with the amount of goals we're scoring.
"Ryan Lowe and Nicky Ajose are getting all the goals but the most improved player since I've been here has been Damien Mozika. Alan Knill always said he was a good player and now I can see why for myself.
"Promotion is in our own hands, we've just got to go out and do the job against Burton and Barnet in our next two home games. I'm not sure if it's good to be playing teams at the bottom end of the table but we've taken three points and I'll be looking for six more points in those next two home games."
