Graham Westley felt his Stevenage side were their own worst enemy as they fell to a convincing 4-1 defeat at MK Dons.
Patrick Bamford's brace plus a superb improvised finish from Dele Alli as well as a Shaun Williams penalty - after Sam Wedgbury had tripped Alli in the box - handed the Dons a comfortable victory, with Darren Potter's own goal the only blot on their copybook.
"We were masters of our own downfall," Westley said. "You can see youth and inexperience in our team and we've made three catastrophic mistakes, then we're 3-0 down.
"The most pleasing thing for me through the afternoon was the response to that because we've got a lot of youngsters learning at this level but they showed good character when it was tested.
"We dug in, we got to half-time clean and we've managed to get the goal that I asked them for at three-nil down.
"I felt really harshly treated with the penalty. I saw the shirt pull outside the box - if it went on into the box then the foul happened outside.
"In the latter stages of the game we had always banked on the fact they would tire and we would come strong and sure enough, as the game wore on, we became by far the more threatening side."
