The Iron matched Stevenage formuch of Saturday's 1-0 loss, with Knill feeling his side had performed well enough to merit a point.
“I thought we did enough to come away with something, but if I’m honest I’ve been saying that every week. We are all just so disappointed, but we obviously have to be better,” he said.
“We’re getting done by goals and up until the goal, considering we were playing second in the league, I thought we looked quite comfortable. In the first half, the only time they looked dangerous was when we gave them the ball.
“I think we defended better, but when you look at the stats it’s the same every week. The opposition won’t have too many shots on target, and yet we’re losing. We’re conceding too easily.
“For 10 minutes after they scored, we were all over the place, and everyone wants to do their own thing, instead of just keeping a basic shape As I keep saying, it’s about goals at one end and goals at your end, and you just have to keep them out."
Stevenage boss likened Greg Tansey to David Beckham after his free-kick decided the game in favour of the home side.
“It was absolutely plumb. He has got a fabulous technique and it’s almost Beckham-esque," he said.
“He’s out there regularly practising those free-kicks and, even though it was slightly further out than he would have liked, he’s so confident, and he works ever so hard at them, that it wasn’t a surprise to see it plant right in the top corner."
