Neil Harris has highlighted the need to carry the buzz from Saturday's Emirates FA Cup victory over Everton into this weekend's Sky Bet Championship return against Rotherham United.
Paul Warne's side visit The Den to face an in-form Millwall side, and Harris is upbeat ahead of the contest.
"We need to carry into the weekend the performance, result and euphoria from last Saturday. We have to use our momentum from the fact we have 10 points from five games, along with two home wins in the Cup," Harris told millwallfc.co.uk.
"We have to play off the feel-good factor at the club, and the players are enjoying training and in form, with the fans behind the team. This game will be as tough as the previous recent fixtures we've had, and the table reflects the importance of the fixture here.
"The aim and challenge here is to put some daylight between ourselves and Rotherham in the League."
The boss has outlined what he expects from The Millers, and has discussed the potential selection headaches he must deal with as Cup-tied players return for the game.
"Rotherham are a physical side who are direct and like to get the ball forward, similar to how we've often played this season. We have to compete physically at The Den like we have done - they will be a real threat from set-plays and long throws - and we need to also use the ball well and be creative.
"The team that played against Everton with enforced changes were excellent, as was the team who played at Middlesbrough. The competition in the squad is there, and you have to play well to stay in the team. We need players at their best as they have been.
"It might be a bit soon for the injured players to come back in, but it's a nice position to be in to have those decisions to make. At the moment, we go into the game with a lot of confidence and in a really good place."
Harris finally touches on The Lions' pairing with AFC Wimbledon having beaten Premier League Everton, and has pointed out that a huge opportunity is at stake.
"We're certainly looking forward to visiting AFC Wimbledon," the manager claims.
"Naturally, you're looking at the big clubs left in it and wanting a lucrative draw, but then you want an opportunity to potentially get through. Both ourselves at Wimbledon will look at it as a chance to progress, and we need to remember that a Quarter-Final place in the Cup is at stake.
"We know a few of the lads at Wimbledon, and we expect a good atmosphere in a packed-out ground."
