Michael Appleton wants his side to bounce back in upcoming fixtures following defeat on the road to in-form Wycombe Wanderers.
The Imps boss was pleased with the chances his players created on Saturday but expects them to be more clinical in front of goal.
“We have had some very good chances and we should be scoring goals,” he explained.
“The goalkeeper made some good saves for them but there were a few occasions where we had to make him work harder.
“You have to be ruthless, and you need that killer instinct if you want to be competitive in the top half of this league. You need to score from the chances you get.”
With the Imps facing Manchester United U21 in the Papa John’s Trophy on Tuesday then Oxford United in league action on Saturday, Appleton said his side will work hard to pick up positive results.
“It will be a tough week because we will have to play some players in both Tuesday's and Saturday’s games," he added.
“Big games are coming up for us, if we stay on the front foot and stay positive things will happen.
“We were brave to come from behind and play well in the second half against Fleetwood the other week, so we will continue to work hard going into upcoming games and look to bounce back from this result.
“Hopefully we will be talking about a positive result after the Oxford game next week.”
