Mark Kennedy has expressed his pride in the defensive record of his team over recent months.
The Imps are currently unbeaten in nine matches and have picked up 14 clean sheets across the season.
Kennedy said: “I made it clear when I joined that football is about what you do in and out of possession. I take great pride in the number of clean sheets we have and how good we are without the ball.
“We weren’t building a team for the first game of the season and we’re still not building a team for Cheltenham on Tuesday night, but we are constantly evolving and have got to the position we are in through eight months of hard work and putting the building blocks in place.”
City’s head coach has also credited the side’s strong form to the hard work his players continue to put in despite a busy fixture schedule.
He added: “We’re not one of the top teams in the league in terms of budget, but collectively we’re a very good group.
“We have to be at our maximum in every game, and we haven’t won a match all season where we have failed to give every ounce of blood, sweat and tears.
"We’ll have to replicate those levels again against Cheltenham if we’re to have any chance of getting something out of the fixture.”
