Jackett’s side will host Wednesday at Molineux in the Championship tonight, and it promises to be a fiercely competitive game.
The Owls may be out of the running for the playoffs, but they have a strong defensive record, having conceded 35 goals in 37 league matches.
To put that record in perspective, Wednesday have conceded fewer goals that Bournemouth, Watford, Derby County, Norwich City, Brentford, Ipswich Town and Wolves - sides who are hoping to get promoted to the Premier League.
Wolves boss Jackett is fully aware of this aspect of Wednesday’s game and told the club’s official website: “Sheffield Wednesday have got one of the best defensive records in the league so they’ll be hard to break down and very competitive, athletic and a very good attitude which we saw in the first game."
Playing at home will give Wolves an advantage, but the promotion-hopefuls have been struggling of late.
Wolves will head into tonight’s game on the back of a 1-1 draw with Brighton & Hove Albion away from home.
Jackett’s side have not won a single of their three competitive games this month, and they need to return to winning ways.
It will be far from easy for Wolves against a Wednesday side who have lost just one of their last five games and have won their last two away matches.
