Coach John Owens said: "Sometimes you get matches where you don't get what you deserve. We have played numerous games where we have performed well and maybe lost or only got a draw.
"But I have to be honest and say it was the opposite on aturday. We got more than we probably deserved from the match.
"We didn't deserve to lose. Crewe played well and will feel a little but aggrieved not to have got something. On the balance of play a draw would have been a fair result.
"We are happy to take the points and it keeps us going. It is good to keep scoring also, but we know we can do better."
