Carlos Carvalhal says the Owls are looking forward to returning to Hillsborough after being without a home fixture for almost four weeks.
The 1-1 draw with Sunderland on Wednesday 16 August was the Owls’ last outing on home soil.
Since then, Wednesday have played three consecutive games on the road and collected four points from the two Championship fixtures with Fulham and Burton.
“It seems like we played our last game here three months ago! But we are very happy to feel the sensation of Hillsborough again tomorrow,” he told swfc.co.uk.
Carvalhal will watch the game from the directors box having received a two-match touchline ban following the Owls’ EFL Cup-tie at Bolton last month.
He said: “Obviously I am not pleased with this situation but I am like all the coaches who feel the emotion of the game and the emotion of the moment.
“My instinct was to protect my player, which was the situation at Aston Villa last season.”
With the transfer window closed and Wednesday’s new additions bedding nicely into the team, Carlos says the energy and vibe on the training pitch has been excellent in the week.
Midfielder Jacob Butterfield and defensive duo Frederico Venancio and Joost van Aken are eligible to play after their switch to Hillsborough in the last window.
“I prefer to look to ourselves rather than the opponents and I will tell you why.
“We have closed the transfer window, which is something very good. We have achieved players that we needed to the team.
“We are really very, very happy with the players we brought to the club. They are adapting and adding value to the team.
“We are training very well, very positive, with a good vibe and good energy and we are looking forward to be back at Hillsborough because we miss a lot to play in our stadium.
“All the teams are difficult, we don’t have easy games in this competition.
“Nottingham Forest are a team that have changed a lot, brought in a lot of new players, made a good start to the season and it will be a tough game.
“But it will be a very difficult game to them also because we are at home, in a positive and strong environment with our fans and we are looking forward to the game.”
