Mark Robins says that his side "did not deserve" to fall to their third defeat this season at the Ricoh after a 1-0 defeat to Mansfield.
Alex MacDonald's late strike was the difference between the two sides after he managed to beat Lee Burge from long range.
"We had plenty of chances,," said Robins.
"Their goalkeeper has made some good saves. We have moved the ball okay but we are not building the pressure enough.
"We need that extra pass. We need to be a little bit more creative and a little bit more careful in the final third. We tossed a few of the balls away when we did not need to.
"Having said that we have creating some really good chances. Some really good chances.
"We dealt with Danny Rose well in the air. He won a couple of headers in the first half but we dealt with him well on the whole.
"They would have been happy with a draw but they are leaving with all three points and that is a massive dissapointment, but we have to take it on the chin and be stronger for it.
"We knew what we were up againt today and we tried to make the most of it. I thought it was a very difficult game for the referee."
Jordan Ponticelli came close on two occassions for Mark Robins' side, twice forcing strong saves from Mansfield 'keeper Conrad Logan either side of the break.
"We have to be more ruthless. We have a very young forward [Ponticelli] in this side so I am not going to be overly critical of our attack.
"It is easy for me to look at his chances afterwards. One, his first touch is taking him across the defender but then he hit it, when if he would have gone across him more then it would have been either a penalty or an open-goal, but he is finding this space in the box which is fantastic."
He added: "I still believe that we are the best side in the division. We just have to work out the best way of finishing moves off. It is a dissappointment because we should be three points better off today."
