Read our guide to Saturday's game at the Macron StadiumNeil Harris takes his side to Bolton on Saturday looking to spark a revival which would see The Lions claw their way back into the fight for a place in the Championship next season.
Chopper is making no promises, and is aware that with his side currently effectively nine points from safety with just 10 games remaining, their chances of survival are already being written off in some quarters. However, he is determined to breathe life into the club's ailing fortunes.
Neil Lennon's Wanderers are still looking over their shoulders, being 10 points clear of the drop zone themselves. Their home form has been pretty good with eight wins and just four defeats to date at the Marcron Stadium, but they have picked up just one victory in their previous six outings.
The Lions' recent record is poor, though, with just one point taken and three goals scored in their last six games.
What the managers say
Neil Lennon: "Saturday is a very big game for us now. It's a must win for us. A point at Blackburn would have been fantastic as it would have given us a bit of breathing space.
"(Neil Harris taking over at Millwall) doesn't change the complexion of things for me. We're at home and our form there has been excellent."
Neil Harris: "The players have shown a great attitude this week. We have given them a game plan which they have taken on board and I'm looking for us to get plenty of balls into the opposition box and hopefully enjoy a little more luck in front of goal than we've had of late.
"We have three big games within the next eight days, and I will need to take that into account in my selections, but we have a couple of important players coming back into the group and that will help."
Paris Cowan-Hall (knee), Shaun Cummings (thigh) and Stefan Maierhofer (quad) are all available again after injury for Millwall. Nicky Bailey (back) is set to miss out.
Barry Bannan will return to the Bolton ranks, having been left out for tactical reasons at Blackburn on Wednesday night. Craig Davies, who played 20 minutes at Ewood Park following a two month lay-off, could be set for a first home appearance of 2015.
Millwall just shade things in terms of League meetings between the clubs with 16 wins to Boltons 13 and five matches drawn. However, The Lions haven't beaten The Trotters in the last four encounters, with Neil Lennon's men winning 1-0 at The Den when we last met in December.
