Bayern Munich coach Jupp Heynckes has warned his players against getting carried away following their 9-2 home win against Hamburg in the Bundesliga on Saturday.
The 67-year-old says that the match against Juventus in the Champions League on Tuesday will be "a whole different story".
"Obviously it was important for us to gain further confidence," he told reporters. "We played some textbook football for parts of the game.
"However, it's going to be a whole different story against Juventus on Tuesday because they will play much more aggressively. It was apparent the team had a lot of joy playing today."
Bayern will host the first leg of their quarter-final tie at the Allianz Arena.
