Read our in-depth guide to Saturday's game at The DenMillwall head into Saturday's visit of high-flying Watford looking to secure crucial back-to-back victories as the scrap for Championship survival intensifies.
Last time out The Lions came from a goal behind to beat Charlton Athletic 2-1 at The Den, a result which interim boss Neil Harris will hope to see his side build on against The Hornets, who are well in the hunt for automatic promotion to the Premier League.
Chopper's Millwall side sit seven points from the safety zone but do have a game in hand on 21st-place Rotherham, who face Middlesbrough at the Riverside Stadium this weekend.
What the managers say
Neil Harris: "I'm not setting any sort of points target that I think we will need to stay up because all we are concerned about is trying to win the next game, which in this case is Watford. They are a really good side and will provide us with our biggest test so far. We are improving, though, and Saturday's game is a challenge the team are looking forward to."
Slavisa Jokanovic: "If we are even a little bit arrogant, and play without any humility or solidarity, then I can expect many problems. It is important that we focus on what is in front of us; to recognise that what has gone before now does not matter and to give Millwall our full attention is the only thing that matters."

Chopper's wide options were boosted this week by the return to training of Paris Cowan-Hall and Lee Martin, who have overcome ankle and foot injuries respectively. It is too soon to say, however, whether the duo will have any involvement in Saturday's match as the interim Lions boss and his backroom staff will be keen to assess the pair's fitness levels in training on Friday.
Nicky Bailey, who came off the bench during the second-half of the win against Charlton, played 60 minutes for Millwall's U21 Development Squad on Tuesday and will hope to be in the squad once again.
Carlos Edwards (knee) remains the only Millwall player currently sidelined with an injury.
Watford midfielder Almen Abdi returned to training this week following a hamstring problem and could feature, though Craig Cathcart (calf) is a doubt.
Fernando Forestieri (knee) looks set to be ruled out while Sean Murray and Joel Ekstrand remain long-term absentees for The Hornets.
Saturday's game at The Den marks the 100th meeting between Millwall and Watford in all competitions.
All but four of those 99 games have been in the League, where The Lions have been victorious on 40 occasions compared to 29 for The Hornets.
Watford's recent record in this fixture makes grim reading for Millwall fans, however, as the Vicarage Road club have won 10 of the last 15 meetings, including a 3-1 success in the reverse fixture earlier this season.
Tickets are on sale to Millwall fans right up to kick-off (3pm).
