Carlisle manager Greg Abbott felt his side's much-improved second-half display deserved a point in a 1-0 home defeat to Peterborough.
Carlisle were unable to get into the game and it was Peterborough who grabbed a 32nd-minute lead when Aaron Davies won possession just inside the Carlisle half and his through-ball enabled Craig Mackail-Smith to race clear and coolly slip the ball past goalkeeper Adam Collin from just inside the box.
Abbott said: "My disappointment is tempered by the fact that we didn't look good enough in the first half. But in the second half we created problems and maybe deserved a draw.
"It just didn't happen for us. We shook things up at half-time and told them to believe in themselves and play with more tempo and passion. I think if we had got a goal we might have turned them over, but all credit to the opposition.
"Peterborough were stronger, tougher and quicker in the first half, which is why we changed it and the response was terrific. All it lacked was a goal.
"Peterborough certainly have firepower and our back four kept us in the game at times."
