Six points from a possible nine is a reasonable return for Millwall, although they have some issues to address after Saturday's traumatic trip to the south coast.
Alex Neil's side started strongly against Southampton and forged ahead with Mark Sykes' 15th-minute strike.
But they were 2-1 behind by the break and crumbled in the second half as their opponents showed why they are among the promotion favourites by running out 5-1 winners.
Wrexham were in action the night before at home to Birmingham and were forced to accept a 2-1 home loss to the West Midlands side.
The Red Dragons had high hopes before the start of the season but they have taken just two points from their opening three games and will be keen to avoid becoming further detached from the top end of the table.

Best Bet - Millwall @ 6/5
Millwall fell below their usual standards in the heavy defeat at Southampton, but they have a habit of responding well to setbacks and can seal a victory over Wrexham on south London soil.
The Lions haven't experienced successive defeats since last December when they followed a 3-1 loss at home to Hull with a 2-0 reverse at Blackburn.
And there was some context to the defeat at Southampton with first-choice goalkeeper Lukas Jensen sustaining a quad injury a couple of days before the game.
However, Millwall's backup keeper Max Crocombe made 23 appearances in the Championship last season and he could not be blamed for the team's uncharacteristically poor display.
They have the chance to atone in front of their home fans and a more focused performance could give them the edge over Wrexham, who are yet to get into their groove.
Wrexham have made a lot of signings intending to build on last season's seventh-place finish, but they were far from convincing in Friday's 2-1 loss at home to Birmingham when they showed vulnerability in their penalty box.
Birmingham scored with two headers, and a physical, direct Millwall side will have noted their success, and are perfectly capable of exposing Wrexham's soft centre.
Alternative Bet - Mark Sykes anytime assist @ 7/2
Right back Mark Sykes bagged his first Millwall goal in the loss at Southampton and could have a key offensive role to play against Wrexham.
Sykes played as a winger or a wingback for his former club, Bristol City, and is already showing his attacking instincts in a Millwall shirt.
He has created five chances in three league appearances and may not take much longer to deliver his first assist of the campaign.
Josh Coburn to score anytime
Over 2 goals
Ben Whiteman to be carded
Pays 16/1
Millwall have been hampered by Mihailo Ivanovic's injury absence, but they have strong centre-forward options in Josh Coburn and Lyndon Dykes.
Coburn has risen to the challenge, scoring a match-winning double in the 2-0 victory at Bristol City, and he can add to his tally in Wednesday's midweek match, which promises to be a high-scoring affair.
Wrexham have looked vulnerable in defence, but they have plenty of offensive talent and have an extra option now that Josh Windass is back from injury.
The north Wales side could score for an eighth successive league game, but it might not be enough to seal any points.
A physical game is on the cards, but that shouldn't concern tough-tackling Wrexham midfielder Ben Whiteman, who has reached a double-figure caution count in three of the last five second-tier campaigns.
