Owls pace ace Jeremy Helan says Wednesday must get back to what has served them well throughout the campaign.
Defensively, Wednesday have been one of the toughest nuts to crack in the Championship, particularly away from home where the Owls have conceded just 15 times.
Only Middlesbrough and Bournemouth, who are first and second in the division, have conceded less (12) on their travels.
After back to back away defeats, Wednesday posted a point in the goalless draw with Brighton last weekend and are now within three clean sheets of equalling an all-time club record.
Helan said: “We know defensively we’ve been very good and hard to beat and that’s what we need to get back to.
“We got another clean sheet last week. Maybe that was the first step.
“The second step is to go to Derby and score goals to get the win because that’s how it goes in this league.
“We’ve got to trust each other that we can do it. We know how good Derby are but nothing has been won yet.
“We’ve got to go there and be positive and maybe surprise a few people.
“There are 15 games to go, we’re not yet on the final straight and we want to make the most of it.”
