Bradford City are the visitors to the Lane in the Premiership just 48 hours after we bowed out of the FA Cup to rivals Arsenal.
With the players still visibly upset by Sunday's events, our Norwegian hitman revealed: "The mood isn't the best of course but I think we're lucky to have a game coming as soon as it is.
"If it was seven to 10 days later it would be dragging on but instead we've had to prepare for this one straight away. We have to switch on, try to put the semi-final behind us and try to bounce back with a good performance and three points.
"We all want to get the semi-final out of the system. It will be good for us to get back on track again."
Steffen also insisted that the season was far from over with some huge games still to come. "We play Sunderland, Chelsea at home next week, then Liverpool and we also have to play Manchester United. So there are some big games. We just have to go out there every game, aim for the three points and try to get up the table."
And it is certainly far from over for Steffen, who is delighted to be back in action after missing a big chunk of the campaign with knee problems.
"If anything there are too many games! It's been two a week for the last couple of weeks because I also have internationals," he added. "But I pleased to be playing and I just want to get a few goals again."
We are 15/2 to record a second consecutive 3-0 home win - click for details.
Steffen Iversen is desperate to get back into action and put Sunday's semi-final disappointments behind us.
