Flitcroft and his side are in search of another three points following last weekend's win over Middlesbrough, to make it back-to-back victories.
"They've conceded a lot of goals, that's what the facts tell you," said Flitcroft of Sheffield Wednesday. "They're a strong, physical side. They've brought in two quality players in Matty Fryatt and Stephen McPhail. Dave Jones has been quietly going about his business building a team he believes in.
"He knows exactly what he needs to get them out of trouble."
There are three absentees for the weekend, including Peter Ramage, Luke Steele and Lewin Nyatanga, as Flitcroft continued, "Again we’re looking strong,” said Flitcroft. “We’ve had players come through this week. Tangs (Lewin Nyatanga) has got more training time in.
The Owls are in search of their first win of the season as they arrive at Oakwell for the 12:15pm kick-off on Saturday.
