City head coach Michael Skubala was pleased with a point against Peterborough United but again felt his side could have got more from the game.
The Imps drew 0-0 with high-flying League One opposition for the second week in a row, this time against the second-placed Posh.
He said: "Peterborough are a top team. They're great with the ball, score some good goals and get after teams really well. We knew we wouldn't have more possession than them. This was similar personnel to last week but different shape to try and stop them.
"We were looking to play on the counter and we thought we could have hurt them on that. In the end, after 90 minutes, we had some big chances again.
"Whatever shape we try to play, we have to be aggressive still and not be passive. We've worked on it with the lads and they get it now. The fans got us through it at times, but we have to take the chances and win games."
Skubala had praise for the Imps' backline, as they kept a second successive clean sheet against promotion-seeking opposition.
He said: "The backline were phenomenal, with Alex Mitchell making big tackles at the end, Adam Jackson controlling it and Sean Roughan stepping out.
"They open teams up all the time and today they couldn't do that. They went to a back three or back five at the end, which was a compliment as they couldn't find a way through and relied on big diagonal balls.
"We're pleased we've got a point but it could have been more with a couple of chances we had."
Updating on the fitness of Reeco Hackett and Ted Bishop, who both came off, he added: "Reeco has come back from a long-term injury and has now played 45, 60 and 90 minutes. He was just tired at the end but we're sure he'll be fine.
"We need to assess Ted. He's been great so far, but he felt his hamstring or back so we've got to be careful with him."
