Luton eased to their biggest triumph of the campaign with a much-improved display and now host fourth-placed Lincoln City on Saturday.
Lawless now hopes Hatters’ midweek victory will serve notice to the rest of the division, as he said: “We would take a 1-0 win every week to win the league.
“But when you do have three goals and a clean sheet, it’s good to put it out there to the other teams who are going to come here.
“No game’s easy and we’re fully aware of that, so it’s now time to rest and get back to training for Saturday.
“We all look forward to playing at home, it’s a great crowd, so it was nice to put it out there.
“We’ve most definitely got to kick on now. It’s just one game, but it could be an important game.”
Striker Paul Benson echoed the thoughts of his team-mate and hopes Luton can finally get a run of wins going.
He continued: “That’s what we need to deliver. Good teams manage to do it week in week out, and we’re not going to win anything without consistency.
“We need to get consistency in our game and we’ll find ourselves moving up the table.
“That’s what champions and winners do, you don’t win this league if you’re inconsistent.
“That means back-to-back wins, and a win on Saturday.
“We can respect Lincoln, but we need to win the game.
“It’s a home game, we’ve seen these two home games as six points and we need to achieve that.”
After easing past the Darts on Tuesday, thanks to a first goal from Benson, the striker doesn’t want a repeat of Town’s shoddy display at Wrexham on Friday night.
He said: “It would be very disappointing if we went out on Saturday and put in an abject performance.
“We’ve got a lot to build on, goals, a decent performance, a lot to be confident about.
“All the elements are there to build on and we need to do that. Teams who win leagues do that and are very professional in what they do.”
Hatters were finally back amongst the goals in the week after the 2-0 defeat at the Racecourse Ground, as they increased their tally to eight from nine games this season.
Benson is hoping for more of the same against the Imps this weekend, adding: “We’ve got to start scoring goals, you don’t win anything if you don’t score goals.
“We’re looking good at the back, looking organised, looking strong. Tyles (Mark Tyler) is marshalling his defence.
“We just need to start scoring more, being more creative, we did that in parts.
“Let’s not get carried away though, let’s look to Saturday and see if we can put in a winning performance with some more goals.”
