Dave Jones was unable to strengthen his team before the loan deadline but insists he has belief in the current squad.
He expects the relegation-threatened Owls to “fight and scrap” and admits there is “no hiding place.”
Jones was interested in signing players who could go straight into the side and “make a difference.”
Efforts to land men who were available, fitted the ball and were affordable proved fruitless.
Pre-deadline moves did see Chris Maguire loaned to Coventry until January 5 and Seyi Olofinjana’s month-to-month agreement extended up to and including Boxing Day.
Wednesday will hope to avoid further injuries in the defence department, with three centre halves injured: Anthony Gardner, Martin Taylor and Kamil Zayatte.
Jones has Reda Johnson and Lewis Buxton as emergency cover for the current partnership of Roger Johnson and Miguel Llera, who are set to face Blackpool tomorrow.
It is also possible to sign free agents at any time.
Jones said just before the deadline: “It (a signing) has got to be somebody who makes a difference, not just somedody who comes in as cover. If we don’t get someone in, we’ll go with what we’ve got.
“Everybody in this club knows what they have to do: there’s no hiding place; they have to fight and scrap.”
When asked if he feels the squad can get the club out of trouble, he said: “I do, but one or two have to look at themselves and not blame others.”
Meanwhile, Jones has called on any player found guilty of match-fixing to be banned for life. An investigation is being held into an alleged scandal in a very low tier of the English game.
Jones, who has never experienced any suspicions of such wrong-doing during his playing and management career, said: “If I found out a player had tried to fix a game, I would tell the authorities. I wouldn’t hesitate.”
