All you need to know about Saturday's game
Spectators of tomorrow's clash between Swindon and Millwall may well witness a war of attrition between managers as well as players at the County Ground, as both team bosses seek to defend their impressive records in the run-up to this weekend's meeting.
Neil Harris will be exuding his usual air of quiet confidence after his side's almost perfunctory 3-0 win against Blackpool last weekend, underlining Millwall's steady and inexorable improvement as the season progresses.
With only one defeat in 11 outings Chopper will be hoping to extend the recent trend against an opponent experiencing their own recent renaissance in form.
Swindon Head Coach Luke Williams is in ebullient mood after receiving a ringing endorsement from his club with a new five-year contract, and an impressive 12-point haul from their last four games.
The Robins last outing resulted in a 2-0 win against Doncaster Rovers, against whom The Lions managed a 1-1 draw a fortnight ago.
What the managers say
"Swindon have moved away from any relegation worries they had early in the season to be a real force. Whether they are close enough to put a run together to make the Play-Offs only time will tell, but with their current position, they can play with some freedom and express themselves which makes them difficult opposition.
"They have some real attacking purpose to their team and we will have to be at our best to deal with them and impose ourselves on the game."
Millwall boss Harris will once again be without defender Joe Martin, who serves the second of a two-game suspension following his 10th booking of the season in the 0-0 draw with Wigan Athletic.
Carlos Edwards, who stepped in to fill the vacant left-berth last weekend against Blackpool, was forced off injured early in the second-half of The Lions' 3-0 win.
The experienced defender will be assessed ahead of kick-off at the County Ground. Shane Ferguson dropped back from left midfield to defence in Edward's absence for the last half an hour of the Blackpool game and provides an option for manager Neil Harris. Centre-half Mark Beevers has also played at left-back this season and is another possibility should Edwards be ruled out.
Millwall welcomed midfielder Ed Upson back to the squad last weekend following a three-match spell sidelined with a hamstring injury and he is again included in the travelling party for Saturday's game.
The two teams have met 95 times to date with The Lions holding a narrow advantage over Swindon with 38 wins to The Robins 31, with 26 games ending in a draw.
However, recent encounters tell a very different story with The Lions showing a clear dominance over their south-western opponents.
The statistics will make grim reading for Swindon supporters who would need to cast their minds back through the mists to May 1985 to recall the last time their team took maximum points off their London opponents. On that day The Robins ran out 2-1 winners.
Since then Millwall have been in imperious form with subsequent encounters resulting in four wins and two draws for The Lions.
Neil Harris was a second-half substitute the last time the two teams locked horns at the County Ground in October 2009. On that occasion, Town's Scott Cuthbert handed the home side a 15th-minute lead before they were reduced to 10 men following the 27th-minute dismissal of Jonathan Douglas.
It became 10 v 10 with just under half an hour remaining when Millwall defender Andy Frampton was sent off and Kenny Jackett's side looked to be heading to defeat.
However sub Danny Schofield popped up with eight minutes remaining to plunder a point for the visitors in a season that was to finish with The Lions defeating The Robins 1-0 at Wembley in the League One Play-Off Final.
Last time we met
Jed Wallace, who hit his first goal in a Millwall shirt in last weekend's 3-0 victory against Blackpool, is listed at 10/1 to open or close the scoring, or 3/1 to grab a goal at any time during the 90 minutes.
