Quinn laments defending
Town missed a 90th minute penalty and Luke Rodgers also misfired when through one on one.
Quinn was also worried about the overall mood amongst the squad. He said: 'At the moment we don't seem to believe that as a team we are going to win, it's something we need to address.'
The boss identified a third area for work as well, 'We had 15 corners today and we've only got on the end of one of those and that's ended up with a penalty for us if your getting that many corners we need to be getting more out of it', he said.
Town'snext game is at home against Cheltenham on Tuesday, k.o 7:45.
