All you need to know about tonight's game
Millwall head to Southend United for tonight's JPT Southern Area Semi-Final gunning for revenge - and a first ever win against The Shrimpers in a Cup competition.
The two teams have already met this season back in September at The Den, when goals from David Mooney (39mins) and Adam Barrett (49mins) either side of half-time secured a 2-0 away win for Southend.
The Shrimpers also tasted victory on the two occasions that they have faced The Lions in previous FA Cup encounters, most recently a 4-1 success at Roots Hall in January 2014 when The Lions played over half the game with 10 men following Jermaine Easter's first-half dismissal.
Phil Brown's Southend go into action on the back of a five game unbeaten run, but have also not yet conceded a goal in this year's JPT competition having beaten Crawley (3-0) and Bristol Rovers (1-0) on their way to the Area Semis.
On the other hand The Lions have lost three out of their last four games, including successive defeats on the road at Fleetwood (2-1) and Burton (2-1).

What the managers say
Neil Harris: "Our away form has been superb up until the Fleetwood game, where we were poor and got beat and then at Burton where we controlled the game and lost. We need to get back to winning ways on the road and this is a good opportunity. It's a challenging one against a good team, and a team that has done well of late.
"The challenge to the boys after Saturday, when we were below par against Wycombe, is to get back as quickly as we can to our usual standards."
Phil Brown: "There's some quality players that we are missing at the moment, but the ones who are playing, you have to take your hats off to them.

"They are pulling up trees for the club and wearing their shirts with pride and that's key."
Team news
Lions boss Neil Harris welcomes back a trio of players who missed Saturday's FA Cup tie against Wycombe Wanderers.
On loan stars George Saville and Shane Ferguson were both ineligible to play in the Wycombe match with their respective parent clubs of Wolves and Newcastle United not giving permission for them to feature.
Centre-half Mark Beevers, who also sat out the weekend game after serving a one-match ban for picking up five yellow cards this season, is able to return.
However winger Fred Onyedinma, who was forced off after appearing to get a knee in his back during the Wycombe match, is a doubt, whilst midfielder Jimmy Abdou got 60 minutes of match action under his belt with the U21s on Monday afternoon following a spell sidelined with a shoulder injury.

Southend manager Phil Brown is able to call on the services of winger David Worrell who missed the goalless draw against Wigan last time out after suffering concussion in United's recent 5-2 win at Oldham.
Tonight's game could come too soon for Noel Hunt, sidelined for three months with an ankle injury, but the striker hopes to return to action at Bradford on Saturday.
Michael Timlin is hoping to return to contention following a foot injury, but remains doubtful, as is fellow midfielder Gary Deegan (ankle).
Anthony Wordsworth (ankle), Myles Weston (Achilles), and Steve McLaughlin (ankle) are definitely out.

Striker Joe Pigott, on loan from Charlton Athletic, is top scorer this season with five goals and may get a chance instead of ex-Addick David Mooney, who has hit four goals.
Head to head

Millwall's last victory at Roots Hall came on 3rd March 2009 courtesy of Gary Alexander's 39th-minute winner.
When we last met
The ink on the last match report for these two teams is barely dry having taken place a mere seven weeks ago back in September.
It was a frustrating encounter for Neil Harris' boys whose occasional flashes of brilliance were thwarted by an impressive display in the Southend goal by keeper Daniel Bentley.
It was the visitors who would go in at half-time with a spring in their step and a goal to the good. Midfielder David Worrall whipped in a cross which was met by striker David Mooney at the near post and his clinical header put The Shrimpers in front.
It took Southend just four second-half minutes to double their lead when Michael Timlin's cross was met by the head of Adam Barrett, who gave the Millwall keeper no chance.
A flurry of substitutions followed from Millwall, but despite a spirited display, The Lions were unable to break down the Southend defence. Steve Morison, Aiden O'Brien and Shaun Williams all went close but were up against a keeper in inspired form.
