Former Netherlands boss Bert van Marwijk has hinted at his interest in the vacant managerial post at Wolfsburg.
Wolfsburg recently parted company with their coach Felix Magath as a result of the club struggling in the relegation zone.
Lorenz Gunter Kostner has since taken the reins in caretaker charge of the side and he was on the receiving end of praise after he oversaw Wednesday's 2-0 win over FSV Frankfurt as the club cruised into the last 16 of the German Cup.
Speaking after the result about the warm reception he got from the fans, Kostner said: "Certainly, that is nice. That is also nice for the team. We need to grow together and it shows them I am no coach of the past, but one of them."
Speculation, however, is growing that Van Marwijk, who left his role as Netherlands boss in the summer, could be being lined up as Wolfsburg's next permanent manager.
The Dutchman told kicker: "I would love to return to club football. I believe the Bundesliga is on par with Spain and England. Wolfsburg is one of many interesting locations in the league."
Van Marwijk managed in Germany with Borussia Dortmund during the years which saw the current champions fight with bankruptcy. He also coached Nuri Sahin, debuting as the youngest player ever in Bundesliga history.
Meanwhile, Danish centre-back Simon Kjaer has said he was relieved at the news of Magath's exit, explaining: "It was a new beginning for me, no doubt, and it was a very good start.
"Before I did not have the chance to play in my position. I believe, I took the chance in Dusseldorf [his first game as a centre-back], that is my position.
"It was not easy to be out, all the time having the feeling I could help the team. Ever since my return in the summer [from a one-year loan spell with AS Roma] it was a tough mental test for me. But I have learned from that and it will make me a better player."
