MILLWALL recently saw their long unbeaten league run come to an end at Swindon, and lost a second game in a row on Tuesday night against top-of-the-table Sheffield United.
Scunthorpe were top of the league after a 3-0 win over Millwall in December, but are now fourth, seven points above the Lions.
A 3-2 win over Bradford last weekend lifted spirits as Newcastle loanee Ivan Toney grabbed two goals.
Lucas Ball spoke to Iron fan Harry Parker ahead of Saturday's all-important tie at The Den.
Why do you support Scunthorpe?: As a young boy, I was a Liverpool fan.
It annoyed me that I could never go to games and I never saw any live football, so I decided to make a change and I have been a season ticket holder at the Iron for five years now, loving every minute.
When Scunthorpe beat Millwall in December, they went 19 points above Millwall in the table. What's gone wrong since then?: Since that comfortable victory at Glanford Park, seemingly everything that could go wrong, has gone wrong.
We must have seen six or seven late goals scored against us to prevent us from taking anything from games which has been very frustrating.
This of course includes the bizarre three-penalty incident at Gillingham [when Josh Wright scored three times from the spot in the last 13 minutes for a 3-2 win] which I had to endure.
Basically, we looked bereft of all confidence but are looking slightly better at this point and I'm travelling to The Den on Saturday in a very optimistic mood.
After beating Bradford last weekend, how much of a boost will that be for the Iron?: I hope that victory will be a massive boost.
I hope that re-instilled any lost confidence from the previous three months back into the players.
The heroics some of those players performed was incredible and showed they are all still fighting and I am simply hoping we can continue that with a win on Saturday to begin pressuring those automatic spots again.
Who are Scunthorpe's most dangerous players at the moment?: In terms of attack, Matt Crooks is on fine form at the moment after scoring two winning goals in our last three matches.
Paddy Madden and Ivan Toney are both in fairly good form after Madden scored a wonderful goal away at Oxford United and Toney scored two of the three goals against the Bantams last weekend.
These are the three players I'll be watching closely and expecting big things from on Saturday afternoon.
Who will you be keeping an eye on from the Millwall side?: I'll be honest, my knowledge of other League One clubs isn't fantastic but I'm sure Steve Morison will be a danger along with Lee Gregory.
I've also heard good things about Shaun Williams, so I hope our lads can keep those three fairly quiet.
What formation and line-up do you expect Scunthorpe to play?: I expect us to play a simple 4-4-2 as that seems to be standing us in good stead over the past few weeks as the confidence returns.
I expect the line-up to be as follows: 1. Luke Daniels; 22. Conor Townsend, 5. Murray Wallace, 6. David Mirfin, 33. Jordan Clarke; 11. Josh Morris, 8. Stephen Dawson, 30. Matt Crooks, 16. Hakeeb Adelakun; 9. Paddy Madden, 24. Ivan Toney
Finally, a score prediction?: Millwall 1-3 Scunthorpe United.
I think you'll score due to our recent frailties at the back, but I think our attacking power will be too much and it'll be a fairly comfortable day for us in South Bermondsey.
