you are a bit wrong. Porto winning 3-1 was surely a surprise but Porto is in the CL for a reason...they have quality and they did not make the quarters by being a bot-team pushover. They consistently win their league and are a farm team for some of the worlds best players. Plus Robben and Ribery were missing in a game played in Portugal where Porto are extremely strong.

Porto deserved to win at home and got raped by playing defensive at Bayern. thems the breaks! It was not a troll session.
