Chris Wilder: Northampton Town slide concerns boss
Northampton Town manager Chris Wilder has said his side are in danger of being "sucked into" a relegation battle if results do not improve.
The Cobblers have lost eight of their last 10 games in League Two, slipping from fifth in September to 19th after Saturday's 2-1 defeat by Carlisle.
Wilder told BBC Radio Northampton: "We've got to look over our shoulders.
"We have got players who can win games, as we showed at the start of the season."
Wilder added: "We want the players back who are going to take us forward. We've talked about changes in January that we want to make, but we've got to dig in and get through this period."
Only four teams have scored more League Two goals than Northampton this season, but their defensive record is amongst the worst in the league.
"At the moment, we can't keep the ball out of the back of our net and when we have an opportunity at the top of the pitch, we're not showing the quality we should be," said Wilder, who led the Cobblers to safety last season.
"Zander Diamond and Ryan Cresswell will be the two centre-halves for the future.
"But we need a settled back four, good enough to keep clean sheets. We need Cresswell, Diamond, Evan Horwood getting their games in and a solid back four.
"We're not going away and enjoying our Christmas dinner - we're gutted about how the results are and I wouldn't have anyone in that changing room who didn't care about the football club and results.
"I've got no problem with the criticism we get. You come through it and players have got to come through it."
Wilder expected to have Cresswell (knee) back for the Boxing Day fixture against Bury, but confirmed on-loan goalkeeper Jordan Archer has played his final game for the Cobblers.
"Matt Duke is the goalkeeper from now on," he said.
"We won't be extending Jordan's loan. Matt is good enough to play at this level and the goalkeeping area doesn't really concern me."
