The former West Germany international believes that Bayern must continue their impressive run of form, while not overlooking any competition they are involved inBayern Munich have reasons to smile after being paired with Olympique de Marseille in the Champions League last-eight stage.
The Bavarian giants avoided facing the likes of Real Madrid and Barcelona in the quarter-finals, though they will meet Los Blancos if both clubs progress.
"When you reach the Champions League quarter-finals and are drawn with Olympique Marseille, you can only say: it could have been much worse," Netzer wrote in his column for Bild.
Bayern have rattled off 20 goals in the last three matches to send out a strong message, and Netzer has called on the club to continue to put in such commanding displays.
"Well-balanced, confident, supported by strong some individual players," he noted.
"Bayern have shown themselves to be a functioning team. Now it is necessary to substantiate this impression in the coming weeks.
"For Bayern players, it must always apply that they want to win everything. And if they do not get everything, they aim for the rest.
"That is the demand at the world's top clubs, like Madrid, Barcelona, or Bayern."
