Gary Rowett's men's next game is an away trip to managerless Rotherham United.
Gary Rowett's men's next game will see them travel to Rotherham United, who fell into the relegation zone following their defeat to fellow strugglers Bolton on Saturday. And Robinson believes that they need to show an improvement against those sides that are battling for their lives.
"Our record against the sides near the bottom isn't brilliant so that's something we need to address," he told the Mail.
"We have been better in recent weeks where we have got a great shape and we have punished teams with the quality we have got in attack. We need to do that again."
Despite the club's poor record against the division's current bottom three - having lost to both Rotherham and Charlton previously, while only claiming a victory against Bolton - they still find themselves just three points adrift of the top six. However, if they wish to claw back that deficit, they will undoubtedly need to be more ruthless against the league's out-of-form teams.
Luckily, they have arguably been presented with the perfect opportunity to set the record straight this weekend.
The Millers have not won in their last four games - collecting just one point in that run - and now find themselves without a manager, after Neil Redfearn left in the wake of the side's defeat to the Trotters.
With Rotherham on the ropes, the Blues will be desperate to ensure that they get their play-off charge back on track by delivering a devastating blow to their opponent's survival hopes.
