Wolfsburg could dispense with Pierre Littbarski and bring in another coach for the season run-in after they slipped into the relegation zone at the weekend.
Wolfsburg, the 2009 Bundesliga champions, are second from bottom after a run of just two wins in their last 16 league games.
Former England boss Steve McClaren was sacked last month but that has failed to address the problem, with Littbarski also failing to get the best out of a talented squad.
Wolfsburg lost 2-1 at home to Nurnberg at the weekend and the club are reportedly ready to make another change for the final eight games.
"The situation has of course intensified," spokesman Gerd Voss said. "The club's board will analyse the situation carefully."
Former Hertha Berlin boss Hans Meyer has been suggested as one solution, but the 68-year-old insisted he had not heard from Wolfsburg.
He told Kicker: "There is nothing in it. There has not been a question put to me."
Wolfsburg defender Sascha Riether is adamant, however, that Littbarski should be given a longer stay after admitting the players were underperforming.
The 27-year-old said: "It's not about him, he cannot help it that we do not do the right things. He has been accepted by the team and already has improved things during his time in charge."
