MILLWALL begin their FA Cup campaign at home to fellow Championship side Barnsley on Saturday afternoon.
Both managers are expected to make some changes, with survival in the division the focus for both clubs.
Neil Harris wants to add two players to his squad in January but no deals are likely to be completed prior to Saturday's game.
The last time these two sides met, Paul Heckingbottom's Barnsley ran out 3-1 winners at The Den, in arguably the Lions' worst performance of the season thus far.
Lucas Ball spoke to Barnsley supporter Lewis Robinson ahead of the game.
Why do you support the Tykes?
Well I was born in Barnsley and my dad is from Barnsley and half of my family is. I moved to Sheffield at a very young age and probably should have supported one of the Sheffield clubs (as the other half of my family supported either Wednesday or United) but as a young kid I chose to support Barnsley and it's gone from there.
What's your favourite season following Barnsley?
The promotion season to the Premier League (1996-97) and then the Premier League season are probably the best ever but I wasn't even born! For me, it's the season we were promoted to the Championship in 2015-16.
The first half of the season was one of the worst ever and the second was incredible. We won the Johnson's Paint Trophy at Wembley (beating Oxofrd United) and then defeating Millwall in the play-off final was one of the best days in my life. Sorry!
Will an FA Cup run be helpful or hinder Barnsley, in your view?
Well, the season I referred to in the last answer, the JPT you could argue turned our season around. I'm not saying this will be the case this year and staying up is the priority. But an FA Cup run could add some excitement to the season.
What do Barnsley need in this window?
In terms of signings, we've been screaming out for a striker. The lack of a target man is evident as we're relying on Tom Bradshaw to do that and that's just not his game.
An old head in midfield would be also be ideal as this is a very young squad and sometimes that experience is needed. They're the main focuses.
Which Barnsley players will be important for you on Saturday?
I'm not sure what sort of side will be played but knowing Hecky it will be a pretty strong one.
Lloyd Isgrove when on form is a handful for any defender and on the other wing Adam Hammill can produce magic when he wants to (as you saw at Wembley).
Mamadou Thiam has some flair and was coming into his own in the last couple of games.
Who do you fear from the Millwall side?
Steve Morison is always a threat due to his sheer physicality, attacking-wise. In defence, I really wanted Barnsley to sign Conor McLaughlin as he impressed for Fleetwood over our two legs in the JPT.
What's your predicted Barnsley formation and starting XI?
Well, our two main formations are 4-4-2 and 4-3-3.
Which one we play depends on what side Hecky fields.
If I had to predict, it'd be this:
McCarthy Lindsay Pinnock Fryers
Williams Potts Moncur
Hammill Isgrove Thiam
Finally, a score prediction?
I'm going to have to go for a tight encounter: Millwall 0-1 Barnsley.
