Everything you need to know about Saturday's game
Whilst The Lions kicked off the new campaign by coming from a goal down to beat Shrewsbury Town 2-1 with goals from Steve Morison and a Lee Gregory penalty, the Sky Blues beat fellow League One newcomers Wigan 2-0 thanks to a brace from teenage Newcastle United loanee Adam Armstrong.
Millwall and Coventry City lock horns for the first time since April 2012 at The Den on Saturday with both teams determined to record back-to-back wins in League One.
WHAT THE MANAGERS SAY
"It's early season and every team wants to get up and running. Millwall beat Shrewsbury away from home, which is a huge plus for them. They're off the mark and they'll be thinking like we are, a win could send you top early doors. Tony Mowbray:
"Their fans can create an intimidating atmosphere and your team have to stand up to it."
Millwall manager Neil Harris has no fresh injury worries ahead of Saturday's game, but may field a team similar to the one that started at Shrewsbury in The Lions' League One opener last weekend.
Harris made four changes to his starting XI to face Barnet on Tuesday evening, but is likely to bring striker Lee Gregory back to partner Steve Morison up front after the duo bagged a goal each at Greenhous Meadow.
Full-backs Shaun Cummings and Mark Beevers along with goalkeeper David Forde could all return to the team as The Lions aim to record back-to-back League wins for the first time since August 2014.
Youngster Fred Onyedinma, who came off during extra-time against Barnet, is fit and included in Millwall's squad.
Joe Martin and Aiden O'Brien (both ankle) remain sidelined along with midfielder Jimmy Abdou (hamstring).
The Sky Blues and Lions have met on 56 previous occasions, and there is very little to separate the two teams when it comes down to results.
Millwall sit just two victories ahead, having won 24 games to Coventry's 22, with the remaining 10 matches finishing all-square. The Lions enjoyed a win double the last time the sides were in the same division, during the 2011/12 campaign, when Darius Henderson (2) and Liam Feeney scored in a 3-0 home success and Shane Lowry bagged the winner in the return fixture at the Ricoh Arena.
Defender Shane Lowry popped up with the only goal of the game to secure a 1-0 win for Millwall at Coventry City when the two sides last met on 17th April 2012.
The Lions, featuring a certain young Harry Kane in their ranks, proved excellent value for a victory in an end-of-season run that steered Kenny Jackett's side away from Championship danger to second-tier safety.
Coventry were handed a golden opportunity to open the scoring when Cody McDonald was brought down by Lions keeper MaikTaylor. However the 40-year-old pulled off a fine save to push away Gary McSheffrey's spot-kick just before the hour.
Coventry City: Murphy, Keogh, Hussey, Cranie, Clarke, Clingan, Bell (Baker, 63mins), Norwood, McSheffrey, McDonald, Platt, Dunn, Willis, Baker, Thomas, Bigirimana.
