Neil Harris has urged his Millwall players not to take the foot of the gas in pursuit of teams in the top half of the table.
The Lions, occupying 14th spot, are just five points behind 10th placed Brentford and have an opportunity to close the gap further when Sheffield Wednesday travel to SE16 on Tuesday night.
"We have had a really good run of results recently," Harris told millwallfc.co.uk.
"We are chasing a couple of the teams above us and we can put more pressure on them on Tuesday.
"Sheffield Wednesday is another tough one, they have had some good results of late since the new manager came in and everyone will have to be ready for another big test."
The Lions will want to follow up their third successive away win with a strong performance at home. Despite being unbeaten at The Den in 10 fixtures across all competitions, Millwall's last League win was against QPR in December last year.
"Yes, we want to get back to winning ways at home but we also want good performances," the manager added.
"We didn't play particularly well by any stretch of the imagination at Birmingham at the weekend, but we got the three points. In saying that, we have been on the road many times this season and haven't got the points when perhaps we deserved to.
"I'll be looking for improvement under the lights on Tuesday."
Harris has no fresh injury concerns ahead of the match. Forward Tim Cahill may feature after stepping off the bench in the 1-0 win at St. Andrew's.
