Porto took a shocking 2-0 lead over Bayern Munich in the first leg of their Champions League quarterfinal on Wednesday, with both goals scored by Ricardo Quaresma and the first coming with a little bit of controversy. 

Quaresma netted the first off of a penalty, which Jackson Martinez earned by picking the pocket of Xabi Alonso at the top of the box and forcing goalkeeper Manuel Neuer into an awkward sliding tackle. 

However, despite being one-on-one with Martinez, Neuer avoided a red card for the foul. Should he have gotten his marching orders?

In any case, the net result was a goal, as Quaresma finished from the spot to put Porto ahead after only two minutes.

If that wasn't shocking enough ,Quaresma would capitalize on another defensive mistake to double the Portuguese side's advantage 10 minutes later. This time, it was Dante at fault.

UPDATE: Thiago Alcantara pulled one back for Bayern, but Bayern's defensive errors continued in the second half. This time the culprit was Jerome Boateng, who allowed a long ball to float over his head and on to the foot of Martinez, who finished easily past Neuer. Pep Guardiola's side have some work to do.
