The Dutchman feels his side must remain respectful of their rivals, while sporting director Matthias Sammer has no fears of complacency
The Bavarians are currently in the midst of a 16-month unbeaten run in the Bundesliga but the Dutchman feels they should still respect rivals by playing seriously.
"A backheel is good if it works, not if it disrespects the opponents," he told Bild.
"We must be careful not to overdo it. We must concentrate on our job. We have to respect the opponents."
Meanwhile, sporting director Matthias Sammer believes that his side are not in danger of becoming complacent when they face Arsenal in the last 16 of the Champions League next week.
"We see every game as hard. We must always put in a top performance. Therefore I have no concerns that we won't find our rhythm against Arsenal."
Finally, midfielder Thiago Alcantara hailed the return of Bastian Schweinsteiger, who made his first appearance since November on Wednesday.
"Basti is an important player and a beast physically. He'll soon put in some strong performances in the starting XI."
