The Lions boss has backed his players to rise to the occasion when QPR travel to The Den on Friday night.
Millwall will see out 2017 with a bang, hosting their London rivals in front of a near capacity crowd.
The fixture will also see the return of Neil Harris' predecessor to SE16, former Lions boss Ian Holloway.
"It's exciting for everyone," Harris told millwallfc.co.uk
"For me personally, he (Holloway) is the ex-manager and having him at The Den will be good.
"It's a London derby and I think the fans are looking forward to it. What I want is an electric atmosphere, plenty of noise and a special environment."
The Lions have been in fine form at home, extending their unbeaten run to four following the 2-2 draw with runaway title favourites Wolves.
"December has been really positive for us and it's about keeping that going," Harris added."
"I was very pleased with our performance and the character we showed against Wolves.
"We conceeded on the stroke of half-time and we could have melted a little bit, but after going behind our reaction was first class and we finished the game really strongly.
"What is going to be key against QPR is a good start. The game will have up's and downs because QPR are a really good attacking side but we have to make sure we are as consistent as possible throughout the game.
The manager may be forced to make changes for the derby. Conor McLaughlin and forward Tom Elliott will be assessed after being forced off with niggles in the Boxing Day match.
"We have to allow people enough time to recover," Harris continued.
"Tom and Conor came off the other day and we will look to get them back involved. You want to give them an opportunity to be fit and if not we have fresh people ready to come in.
"We will leave it as late as possible."
