Bayern came into the game, a repeat of the 1987 European Cup final which Porto won 2-1, ravaged by injuries and robbed of the services of Arjen Robben, Franck Ribery, Bastian Schweinsteiger and David Alaba among others.

It was, however, a different story for Porto, who welcomed back Martinez from a hamstring injury.

The Colombia striker wasted little time in making his mark, robbing a dawdling Xabi Alonso of the ball on the edge of the Bayern box before being felled by Neuer's outstretched leg.

The Bayern keeper was perhaps lucky to receive just a yellow card, but his punishment was swiftly increased as Quaresma stepped up to stroke the penalty into the bottom corner.

There was no time for the visitors' nerves to settle as Quaresma pounced on another mistake, robbing Dante before dashing through and beating Neuer with an expertly-taken finish with the outside of his boot to make it 2-0 after 10 minutes.
