MILLWALL head into a busy Easter period sitting in sixth place in League One, just one point above play-off rivals Southend.
There are just five points between third and sixth, so a lot could change in the final four games.
The Lions will be hoping for their third win in four on Good Friday, after beating Scunthorpe and Shrewsbury before drawing at Priestfield last weekend.
Northampton are in 15th place, six points above the drop zone. Justin Edinburgh took over in January, and he will likely guide them to safety after current Sheffield United boss Chris Wilder won the League Two title with them last year.
Lucas Ball spoke to Northampton fan Tom Reed ahead of Good Friday's game.
Why do you support Northampton?: I was born here. My family are from London and my dad warned me I'd be in for misery if I supported the Cobblers.
He wasn't wrong but there have been some moments of real joy.
Northampton have had a fairly solid season on their return to League One. What has been the key to that?: We have a core of good, solid League One players and a fair few from the League Two title-winning squad from last year.
Our goalkeeper Adam Smith could play in the Championship and defenders Zander Diamond and Dave Buchanan are Steady Eddies and perform consistently.
Meanwhile, John-Joe O'Toole is into double figures for goals from central midfield and striker Marc Richards is an experienced finisher.
The mission was to stay in League One and, touch wood, we've done that.
Justin Edinburgh took over a few months ago now, has there been an improvement under him?: Yes, though that's not difficult given the Rob Page car-crash tenure.
We're more difficult to beat now, though we seem to be more vulnerable to conceding late goals. In all fairness, he's done a decent enough job, and we should be able to look forward to another season in the third tier.
How is Millwall loanee Gregg Wylde doing at Sixfields?: It was a complete waste of time signing him.
I'm not even sure that he's still with us. Like you, we found him struggling to get into the team and when he did he was fairly ineffective.
Who will the dangermen be for Northampton?: For us, there are three real dangermen: striker Marc Richards, midfielder John-Joe O'Toole and former Premier League player Matt Taylor.
Richards is one of the league's best finishers, as Sheffield United found out last weekend. O'Toole has been quality throughout the season and for many years. He has an eye for goal and is now somewhat of a cult figure.
Taylor has some technical quality being a former Premier League set-piece taker, but his pace is definitely at non-league level these days.
Who do you think could have an impact from the Millwall side?: Steve Morison never made the grade at NTFC, and still has a chip on his shoulder about it by the looks of it given his celebrations when he scores at Sixfields.
He's a good finisher and can cause problems with his aerial ability too.
I noticed Lee Gregory has just come back from injury so hopefully we can keep him quiet being one of the top scorers in League One.
Also, Aiden O'Brien is another man we'll have to keep eyes on. If he plays well, his finishing can put teams to the sword.
What formation and line-up do you expect Northampton to play?: Probably a modified 4-4-2 with two big fellas up top in Michael Smith and the aforementioned Richards.
I'd like to see more of Palace loanee striker Keshi Anderson, but he doesn't appear to be in favour with the management.
I'd probably say this is our most likely line up: Smith; Moloney, Diamond, Nyatanga, Buchanan; Anderson, O'Toole, Taylor, Williams; Smith, Richards
Finally, what is your score prediction for this Good Friday fixture?: You can probably put your life on there being more than 2.5 goals in this game.
In 15 out of our last 18 matches there have been three or more goals scored. I'll go for a 2-2 draw.
