Player-coach Graham Kavanagh spoke to us after the Millwall game on Tuesday night.
He said: "It was frustrating for us because it seemed like we were on top for large parts of the game.
"They got their goal and it was probably a little bit against the run of play. Like we've said before, goals change games and they change momentum.
"The keeper has made an unbelievable save off my shot, and if that goes in then it could have been a completely different outcome to the game.
"I thought we started with a decent tempo and I think we knew that we needed to improve from what we did on Saturday. We had the energy and the tempo tonight but we've come away with nothing.
"The positives are that we have crossed and created as many chances as we have done in the last three games, but we have to hold our hands up and admit that the outcome is still zero points.
"We felt that we got back on top after their first goal and we thought there was still something there for us. They work hard and they are very well organised, and they are extremely fit all over the park. They are a very good outfit and I can definitely see them making the play-offs.
"With their second goal, I think it's the easiest thing in the world to criticise the referee, and I don't really want to do it. However, it becomes frustrating with the inconsistency that they have. Some weeks you get stupid free kicks, and to be fair today, he tried to let the game flow.
"Their player has had a look at Adam and he's made sure that he has gone into him, but the referee hasn't given it. It was obstruction all day long because he knew exactly what he was doing.
"We created a lot of chances that were just in front or just behind the players in the box, and we have to look at how we can time our runs better from that. You have to take the positives though, and that is that we are getting into those areas.
"What we have to be clear on is that we have a tough run of games coming up and we need to secure our place in this division. Everyone talks about the points cushion that we have, but we're not safe. We know that ourselves, and we're not going to rest on our laurels until we have done the job.
"We have to give credit to Millwall. They were the better team in terms of organisation on the night, so we have to hold our hands up to that."
