Quotes from the manager ahead of Tuesday's big game
Lions boss Neil Harris believes his side will have to be "every bit as good" as they were during the win over Scunthorpe United if they are to secure a positive result away to Shrewsbury Town on Tuesday night (7.45pm).
Millwall beat The Iron - one of their Play-Off rivals - in comfortable fashion at The Den on Saturday and now face a tough away game against a side battling for survival.
The Shrews could climb out of the League's bottom four with a victory while The Lions know back-to-back wins would increase the pressure on clubs directly above them.
"It's between two teams at opposite ends of the table fighting for very different reasons," Harris told millwallfc.co.uk.
"The common goal is that we'll both be desperate to win the game.
"We go into it full of confidence after the win over Scunthorpe and hopeful that what was a little blip is behind us. On Saturday we played with real intensity, aggression and quality, and we'll have to be every bit as good as we were then again on Tuesday night."
He added: "Shrewsbury are fighting for their lives so it's going to be a difficult game for us. We've seen in recent months when we have come up against teams towards the bottom that they scrap, battle and make things tough for you, so we've got to be at our best and go there knowing it's our biggest game so far.
"As the home side Shrewsbury will have a go at us so we've got to stand strong, defend well and win individual and collective battles. Our use of the ball has to be really good."
