Lambert says he's ready to turn to the Dane following the broken leg injury to Libor Kozak.
After their FA Cup defeat to Sheffield United, Lambert told the club's website: "There's a chance for Nicklas to stake a claim.
"Nicklas did well when he came on. If there's one plus from the game, it was Nicklas coming on and scoring his first competitive goal.
"He has a bit of a hard time since he's been here. But he's a really lovely guy. He's a nice guy.
"It was a good goal. That will give his confidence the world of good.
"It's taken him time to adjust. When you're that young and you're trying to get to the level, some hit the ground quicker than others.
"I was delighted with him scoring the goal."
