Wolfsburg coach Felix Magath questioned his players' fight after their 4-0 thrashing at his former club Schalke.
The Wolves were outplayed in Gelsenkirchen yesterday as their recent run of improved form came to a shuddering end.
And Magath was quick to condemn those he felt had not done enough to earn the visitors a result.
"The team is not allowed to play like this," he said. "We cannot throw away a game as easily as we have done today.
"We stopped playing at 0-1 and that is not on. We have had almost exclusively home games so far in 2012 and we had been playing well.
"We then played a good game in Munich and we had all hoped that the second half of the season was going to be completely different, but today we were the same as before."
Magath has therefore threatened consequences, making it clear that nobody can be sure of their place in the team.
"The problem is, we have behaved just like we did during the first half of the season and that begs the question what kind of a role the established players here play," he told Sky television.
"We have got to ensure that the players learn to take more responsibility for their actions."
Schalke coach Huub Stevens said: "We just made the most of their mistakes.
"All that we can criticise today is the taking of chances."
