Manager Neil Harris and his Bluebirds head north to Huddersfield in midweek aiming to take their points tally to 10 from four fixtures.
They have earned two wins and a draw from the last three SkyBet Championship matches and now take on strugglers Huddersfield Town in Yorkshire on Wednesday, before facing third-from-bottom Wigan Athletic at home on Saturday.
“I’ve told the lads I am looking for six points from these games,” said Harris.
“If we want to have any chance of reaching the top six, we have to beat teams like Huddersfield and Wigan. That’s no disrespect to them, but they are near the bottom for a reason.
“We are up to eighth, which shows just how tight the league can be. If we want to be serious contenders for the top six, at some stage we have to put a little run together.
“Players and staff feel we are so close.
“We were lucky maybe not to be behind against Luton at half-time. The second half was so much better, a lot more professional and some real moments of quality.”
Huddersfield manager Danny Cowley, though, is planning a special welcome for the Bluebirds on Wednesday.
His team defeated Queens Park Rangers 2-0 on Saturday and have secured seven points from their last four matches.
“I have been looking at Cardiff over the last 48 hours, devising the game plans for us to try and earn more points,” said Cowley.
“We have seen Cardiff this season. Neil Harris is somebody I know well, a friend of mine, and he has gone in there at a similar time to me.
“They have got an extremely good squad, are fresh from a 1-0 win at Luton and we anticipate a tough game.
“They are a powerful squad, with a directness about them and it will pose a really good challenge for us.
“But we go into it from a good place as well and it would be brilliant to back-up that win over QPR with another one, brilliant.”
Harris was delighted with Tomlin’s 73rd minute winning goal at Luton, saying: “I was delighted with the quality of the goal, Lee has those moments. A lot of my players have those moments.
“Luton’s main threat was from counter-attacks following our set plays. We talked at half-time about being professional, organised.
“I was delighted with the clean sheet and three points on the road.”
Tomlin scored when he curled home from the edge of the penalty area and the defeat leaves Luton nine points from safety.
Graeme Jones, Luton’s manager, was bitterly disappointed, saying: “We out-possessed Cardiff, created more chances and the boys gave absolutely everything.
“The game boiled down to two moments where Tomlin, he doesn’t hope to score, he makes sure he can score.
“We had a really good opportunity, an incredible one-v-one. You have to take them if you’re going to win the game and we didn’t.”
The big question now is can the Bluebirds follow up a battling 1-0 win at Luton with another away success?
