STEVE Lomas insists Millwall have to defend better as a unit – and that it would be unfair to single out his back four for conceding so many goals.
The 3-1 loss at Bolton left the Lions with the joint-worst defensive record in the division along with Barnsley, who are the next opponents at The Den after the international break.
But Lomas says it will take a collective improvement to keep clean sheets.
He said: "At the start of the season we were conceding goals because of individual errors in terms of people getting done from set pieces and mistakes around our box. At the moment we need to tighten up as a team.
"It is not just the back four, it is the whole unit. It wasn't just the back four who kept a clean sheet against Charlton, so to start pointing fingers would be wrong."
And the Millwall boss says injuries have played a major part in his side's defensive record.
"What does not help is having to make change upon change to your defence, because that is the one area where you really want a bit of continuity," Lomas said. "You want to have a bit familiarity there.
"We were starting to get a settled team and then Scott Malone and Mark Beevers get injured, and it's not like they were short-term things. Beeves was out for six weeks and, although Scotty's isn't as bad, it still causes disruption.
"If you look at Burnley, I wonder how many times they have had to change their back four? We've certainly had more than our fair share of injuries. But like I said, I don't want that to be used as an excuse.
"Regardless of who plays, we have got to get better defensively. A lot of our play is to be admired because we're certainly knocking the ball around better and creating more chances but that all counts for nothing when we concede poor goals.
"If you can keep it to zeroes and ones in the against column, you have got half a chance.
