Caretaker manager Steve Agnew says the Owls have moved on and responded positively after defeat in the Championship last time out at Hull.
Wednesday have got back to business with a strong week on the training ground and victory in a tough cup-tie away at Luton on Tuesday.
As a result of that, Agnew has said spirits are high in the squad as the final preparations are put into place for the visit of Wigan this weekend.
He said: “We’ve done everything like we normally do, our analysis on the opposition, strengths and weaknesses and we’re all prepared and ready to go.
“After the cup-tie the other night, the lads are in good spirits so it will be a good game tomorrow.
“We’ve moved on from the Hull game, we addressed that and got a response from the players at Luton.
“Of course we were pleased about that and on Saturday we’ll have a good crowd, a good atmosphere.
“If we play with the intensity that we can, with the ability that the players are showing and showing us in training, I can’t see why we can’t put in a good performance and hopefully get the three points we need.”
Wigan ended an eight-game winless stretch last weekend with a comprehensive 3-0 victory over Aston Villa and Agnew expects a difficult test from the Paul Cook’s side on Saturday.
“Wigan won promotion last year and then started the season very well,” he added.
“They’ve had a little bit of a sticky patch just recently but they got things back together last week with a really good win against Aston Villa.
“They’ll be in a buoyant mood and be confident after that so it will be a tough game.”
