But Stockport secured all three points on Friday night thanks to goals from James Vincent, Chris O'Grady and a brace from Oli Johnson and Thordarson said: "I'm afraid that my final assessment is that we played against ourselves.
"We conceded too many soft goals, and if you defend like that you just can't win games. We need to be better than that. Sometimes frustration creeps in and it did again and all the goals we conceded were very poor.
"It was absolutely shocking. The players need to show more desire and more guts, everybody is very disappointed down there.
"We have got some decent players, and we did score three goals but when you think about all the chances we missed then that was shocking."
