Watch: Bayern Munich nets five first-half goals to bury Porto

Bayern took Porto, chewed it to a pulp, spit it out, and buried it under an avalanche of first-half goals to turn the tide of the quarterfinal tie into a wave that the German club can surf to the Champions League semifinals.

Porto pulled off the shock of the Champions League quarterfinals last week, defeating Bayern Munich 3-1 at the Dragão stadium in Portugal. 

With Arjen Robben and Franck Ribery hobbled with injuries, many thought Porto had a chance to complete the opposite in the second leg this week, despite missing both of its starting full-backs. 

Bayern took that notion, chewed it to a pulp, spit it out, and buried it under an avalanche of first-half goals to turn the tide of the quarterfinal tie into a wave that the German club can surf to a spot in the Champions League semifinals. 

In a first-half onslaught that in some ways resembled Germany's 7-1 rout of Brazil in last summer's World Cup, Thiago Alcantara got the party started with a simple, close-range headed goal in the 14th minute:

Robert Lewandowski made it a hat trick of Bayern headers, pulling Bayern ahead of Porto on Aggregate after 27 minutes (thanks to a nifty assist from Thomas Muller):

At this point things just weren't going Porto's way, evidenced by Muller's deflected goal to make it 4-0 after 36 minutes (5-3 on aggregate):

Mercy? Hah! Lewandowski got himself another just before halftime to bring the aggregate score to an astonishing 6-3 in favor of Bayern Munich.
