Pep Guardiola wants Bayern Munich to show greater potency in front of goal, despite scoring 18 goals in their last three Bundesliga outings.
The reigning champions hammered Hamburg and Paderborn 8-0 and 6-0 respectively, before a 4-1 thrashing of Cologne in their last league outing.
They hold an eight-point lead over second-placed Wolfsburg, but Guardiola believes there is still more to come.
"We must do better in attack," he said. "In defence we are imperious - opponents have very few chances against us.
"Yes, recently we have scored a lot of goals, but that's because our players are so good. Our overall attacking game must get better."
