Bayern Munich made light work of a 3-1 first-leg deficit as they battered Porto 6-1 last night to sail into the last four of the Champions League on a 7-4 aggregate.
It was supposed to be a night that would test Bayern boss Pep Guardiola's mettle after last week's disappointing defeat in Portugal, but his charges made a mockery of such predictions with five goals in 26 minutes in the first half.
Thiago kicked off the rout by nipping in front of his marker at the near post to nod home from Juan Bernat's superb cross after 14 minutes.
Porto began to fall apart and Bayern levelled the contest on aggregate in the 22nd minute, with Jerome Boateng heading in his first goal of the season.
Bayern's third was truly exquisite, which completed a three-goal 13-minute salvo to totally turn the tie around.
First, Philipp Lahm showed his class with an inch-perfect cross on the volley before Thomas Muller unselfishly flicked the ball onto Robert Lewandowski's head and the Polish striker made no mistake from close range.
Muller twisted the knife with a somewhat fortuitous fourth as his low shot from distance was deflected off Bruno Martins Indi and trickled through Fabiano's legs.
Lewandowski then picked up the ball from Muller around the penalty spot and showed ice-cool composure to fire it home.
Jackson Martinez gave the visitors a glimmer of hope in the second half when he caught Bayern's under-worked backline out to head in Hector Herrera's cross.
But things got worse for Porto when Ivan Marcano picked up a second yellow for a wild lunge on Thiago with five minutes left and Xabi Alonso fired in the free-kick with to complete the scoring.
