Following Monday's mouth-watering F.A Cup fourth round draw, the football club is calling on the support of as many City fans as possible to try and help cheer Phil Parkinson's men onto an exciting trip to Stamford Bridge later this month.
After drawing 3-3 at The Den on Saturday, both Millwall and Bradford City were drawn away to Premier League leaders Chelsea in the F.A Cup fourth round.
The actual opponents for Jose Mourinho's high-flying Blues will be decided a week on Wednesday (14 January 2015) when City and Millwall meet at the Coral Windows Stadium in their third round replay.
This is where you, the fans, can come in and really play your part.
The club is hoping to see a sea of claret and amber around as much of the Coral Windows Stadium as possible that Wednesday night ready to push Parkinson's men onto possible victory.
The complete ticket details for this tie have yet to been confirmed for home supporters so please stick with the official club website and/or twitter/facebook pages in the coming days to find out more information.
Talking of twitter, the club would like, if possible, for fans to help ramp up the interest and anticipation for the Millwall replay by adding the #letsfillthestadium hashtag to any comments made on the social media site about the game.
An excited Parkinson added his own rallying call by saying: “We spoke before the game on Saturday about going to Millwall and having to deal with the environment and atmosphere down there.
"Let's hope we can now give Millwall a taste of what the atmosphere around Valley Parade can be like with a really good crowd on the night.
“I hope the excitement of the draw will bring more people out for the replay. We need to give them a difficult atmosphere to play their football in and that could hopefully give us a real edge.
"We’ve got a really big league game on Saturday against Rochdale and then hopefully we can give everything and win the replay.
"It is a great draw for both sides - probably one of the top ones you could have hoped for. We did half the job down at Millwall and now we're going to give it our all to win the replay a week on Wednesday.
"We've all seen Chelsea play plenty of times on the television in the past, we now have a great incentive of having a chance to possibly test ourselves against them."
