VIEW FROM THE DRESSING ROOM
Alfreton Town manager Nicky Law:
"We have deserved to win that game. They have given us everything they have got and have had attempts from long range. I think Ross [Atkins] has had a save to make early on, but in the second half he has not had a save to make and they have scored from a deflected free-kick.
"I thought my lads were great, and I thought we played some good football. We defended well as a team and I think it's progress when you can see the faces of Cambridge [who] have gone off horrified at half-time and they have come off delighted at the end of the game.
"When the top of the league [team] is delighted with a point here it shows how far we have come."
