The Dane has been out of action with a knee injury.
He told The Birmingham Mail, “It’s [the injury] so frustrating, although the swelling has gone down. I’ve had some treatment over the past few days so I’m aiming to get back to work on the training pitch at Bodymoor Heath this week.
“One thing is certain, though, while I’m desperate to play again, I’ve realised that you simply can’t rush back from injuries like this.
“I had earmarked our game against Manchester United early next month as a possible comeback date. But that will obviously depend on how things go over the next couple of weeks.”
