Silva says there will be no thoughts of heading to the Allianz Arena and settling for a stalemate.
The Spanish playmaker said: "I think we will go and attack them.
"We can stick to our footballing principles.
"We don't have to change our style against other teams — home or away. We believe in what we are doing and have confidence in each other so we will keep doing the same things.
"The truth is Napoli played very well and they are a strong team, but we always try and do our best and keep our style of football.
"Against Bayern Munich we will try the same — to keep the ball, play with the same style and get a positive result."
