Coach Louis van Gaal has demanded more from his Bayern Munich side despite their recent improvement.
Bayern's slow start to the season has been forgotten in recent weeks and on Saturday they ran out 2-1 winners over Nurnberg.
However, the Dutch coach is still yet to be satisfied by the level of performance since arriving at the Allianz Arena.
He said: "We have still got to get more mature. We made a huge error as, when you lead 1-0 after so much hard work, you cannot all go running forward.
"But I am still very happy that we won and I think we deserved to do so."
Meanwhile, Markus Babbel has admitted that he is facing the toughest task of his brief managerial career after Stuttgart lost to Bundesliga basement club Cologne.
Stuttgart were booed off the pitch by their own fans after Saturday's 2-0 defeat at the Mercedes-Benz Arena just days after failing to overcome Rangers in the Champions League.
"For me as a coach, this is my toughest situation so far," admitted Babbel.
"We have got to just take a step back from our aims and get back to the basics.
"We need to return to our values, which we are missing at the moment."Reuse content
