VIEWS FROM THE DRESSING ROOM
Wrexham player-manager Andy Morrell told BBC Radio Wales:
"[I] thought our performance was really good, especially the first half an hour. I thought we were right at it and we had chances.
"[We've] just got to be more clinical but I thought we defended great again. It's another clean sheet. I thought we thoroughly deserved it."
