Stuart Gray says his side must learn a lesson from their previous game with Fulham if they are to equal a club record this weekend.
Should the Owls not concede against the Cottagers on Saturday, it will see them match the club record for most clean sheets in a season.
But Gray says they will have to defend much better than they did when they lost 4-0 at Fulham in December.
“We defend from the front,” Gray said. “Last week at Blackpool we had Atdhe Nuhiu and Will Keane closing down their defence and winning the ball back.
“The games where we’ve struggled are the ones where we’ve not done that and Fulham was one of those.
“We didn’t take any pressure off the back four and the goalkeeper so we need to make sure we do that this weekend.”
Gray admitted he was not aware of the club record until a few weeks ago but he spoke with pride about the potential achievement.
He said: “It’s credit to the players because we aim to defend with 11 men and attack with 11.
“It’s down to the hours of work we put in on the training ground.
“We must be doing something right.
“People used to talk about boring, boring Arsenal winning 1-0 but they were always up there.
“If you keep the ball out at one end you’ve got every chance of winning the game
“But you also have to pop the ball in there at the other end to be up at the top.”
Sam Hutchinson trained yesterday and could feature against the Cottagers as he recovers from a bruised foot.
Jose Semedo, Kamil Zayatte and Sergiu Bus will all miss out.
