Wolfsburg coach Steve McClaren admitted that the "pressure is mounting'' after his third straight defeat in charge of the Bundesliga club.
The 2-0 defeat in Dortmund completed the Wolves' worst ever start to a Bundesliga season and McClaren knows that he must turn things around quickly.
"I knew that it was going to be hard to start with, but it is harder than I thought,'' he admitted. "The pressure is mounting.''
The club's general manager Dieter Hoeness, who has overseen a spending spree of almost €40 million this summer, has made it clear that he cannot tolerate such performances for long.
"The players are playing below their actual ability,'' he said. "It is hard to explain, and I don't only mean Diego. Simon Kjaer is usually far more assured than he is and I know that Cicero is a lot better than this. We are in a critical situation.''
The Wolves are not the only top club struggling as fellow pre-season title candidates Schalke and Stuttgart have also lost their first three games of the season.
