NEIL Harris insists his players will not be intimidated by the Sheffield United atmosphere this weekend.
Bramall Lane is set to be sold out for the clash between one side fighting to stay in the division and another who hope to depart the Championship for the Premier League.
Millwall have an allocation of 1,300 tickets for the clash, as they target a fourth away league win of 2019.
It was a cauldron of noise when the Lions claimed a point at United last season.
"We don't get intimidated anywhere, we don't get fazed by anything," Harris said. "Once you've played at The Den numerous times playing anywhere else is not a problem.
"Nothing surpasses The Den. Elland Road and our start in that game, how well we played, was testament to how we handle those occasions.
"It'll be a great occasion at Bramall Lane, as it will be at Villa Park in the following game, as it was at Elland Road.
"This is why we want to play at this level and get the points on the board to stay in this division.
"I've spoken about what a privilege it is to manage at this level and how important it is for us as a club to play at this level.
"All that matters to us is amassing the points to stay here. Year after year this league seems to get better."
Meanwhile, Ryan Leonard wants his team-mates to "silence" the home crowd this weekend.
Leonard joined the Lions from United last summer.
He said: "There are some tough places to go in this division and the crowds are big, they get behind the team.
"I had a six-month spell there and the fans were brilliant, to be fair. But our job is to try and silence them. We need to start the game right and I think that'll be the biggest thing the gaffer talks about beforehand."
