Shaun Hutchinson scored the winning goal against Derby County at Pride Park on Saturday afternoon - and vowed that The Lions will finish the season as strongly as possible.
The defender headed home his first Sky Bet Championship goal of 2020/21 in the weekend's 1-0 win, during a solid defensive performance which, despite large spells of possession, limited The Rams to few clear-cut chances.
Results elsewhere meant the gap to sixth place currently stands at 12 points with 10 matches remaining, however - but Hutchinson told millwallfc.co.uk that his side will finish the campaign "strongly" and build confidence ahead of next season.
"We want to win every game, no matter what," he said. "It seems as though the season may unfortunately fizzle out now with only 10 games left - that will be a hard gap to close. Whether there's something to play for or not, though, we want to put in a shift no matter what. We want to finish the season strongly and build confidence going into next year."
The centre-back met Jed Wallace's corner on the stroke of half-time in Derbyshire to find the net, but expressed his disappointment at his lack of goals this season - as an individual and a team.
"It was a solid performance from us. At times they pinned us back, but we knew if we had a solid shape then they wouldn't be able to break us down.
"I managed to get the goal from a set-play, which I'm pleased to get. I should've had more, I'm disappointed with my return this year, but it was nice to get off the mark.
"I think that's one part of my game I'm critical about, even as a team I think we've been poor in attacking set plays this year, where we're normally strong. However, on the flip side, we've been very strong defending them."
Next up for Millwall is Wednesday night's trip to Queens Park Rangers, and the 30-year-old is seeking local bragging rights at the Kiyan Price Foundation Stadium.
"It's been quite nice to not have a midweek game! Most of the boys have been going at three games a week for quite a while. But Wednesday's game is a local derby, which means a lot to the fans and a lot to the players, so we're going to go there to win the game."
