Newport County manager Justin Edinburgh told BBC Radio Wales:
"When we're dominating possession and putting the ball into the box and creating chances we've got to punish teams.
"The second half showed that when they had their chances punished us, although they were poor goals, certainly the first one.
"That gave them a lift to go on to win the game. But I'll certainly take a lot of positives from the performance - it's the best performance I've had since I've been here."
