Still opted to go with recent signings Nathan Oduwa and Ryan Hall either side of lone frontman Jayden Stockley, with leading scorer Mark Cullen on the bench once more.
The Town chief said: “What you have to understand is Nathan is used to playing a system.
“If we bring him in and completely change what we’ve seen him do, he probably hasn’t played a 4-4 2 at Tottenham.
“We’re trying to teach him it as we go, but because he’s got match winning skills, you try and play him the best way you can.

“We should have been in front by half time without playing well, as (Andy) Drury should have scored and we had two off the line.
“I thought young Jayden did well again and when I look, we were 3-0 up here against Cambridge 10 days ago, and we had one up front then.
“So it might be more personnel based rather than system based, but we’ll see.”
Still did admit that once Cullen was brought on, along with Shaun Whalley, with Luton swapping back to a more traditional 4-4-2, they looked more threatening, fighting back from 2-0 down to rescue a point.
He continued: “You can’t ignore the facts, and yes we did bring two on.
“But when they went down to 10, we just picked the tempo up incredibly, which is what I was hoping for in the first half.
“Shaun played on Saturday, and he’s done okay in the games.
“He was electric when he came on but he didn’t do that Saturday.
“You can look at it two ways, so maybe giving him a little bit of a rest and bringing him on was the right thing to do.
“We got the goals back and I thought we would win it at the death with Nathan.”
The final result did frustrate Still though who admitted he may make alterations on the training ground.
He added: “Of all the games this season at home, that’s for me probably as disappointed as I’ve been.
“We started the second half okay, but we never kept the tempo up.
“I need to look at that and perhaps need to adjust one or two things in training, as it’s very unlike us not to play with a tempo.”
