Imps manager Michael Appleton is pleased with the performances from this side as they head into a busy period of fixtures.
Tuesday's visit of Portsmouth comes hot on the heels of Saturday's trip to Doncaster - a match Appleton believes his side should have won after controlling large periods of the match.
He said: “We were aggressive in our approach on Saturday and I couldn’t see them scoring - we were very comfortable in the first half and missed opportunities to score or make their keeper work.
“From a performance point of view some of our football was great, but the game is about putting the ball into the back of the net and it doesn’t matter what you do between both boxes sometimes.
"It is two clean sheets on the bounce and we didn't look like we were going to concede so we take the point and move on."
The Imps boss praised the more than 2,300 Imps fans who travelled to the Keepmoat Stadium and expects another good atmosphere on Tuesday evening.
He added: “The fans were fantastic, and they created a good atmosphere because of the amount that turned up.
“I’m sure Portsmouth are going to bring a shedload of fans up as they normally do to away games. I’m sure it will be a good crowd and I’m expecting it to be a great atmosphere.”
