Paris: Doubles from Robert Lewandowski and Neymar inspired Bayern Munich and Barcelona respectively into the Champions League semi-finals on Tuesday.

Lewandowski's brace came in a crazy first half where Bayern rattled five goals past a demoralised Porto side, who had come into the game leading 3-1 after the first leg and with real hopes of reaching their first semi-final since they won the trophy in 2004.

The game ended 6-1 and a 7-4 aggregate victory for Bayern and extending their coach Pep Guardiola's remarkable record in the competition where he has never failed to reach the last four.

Neymar also scored his double in the first half for Guardiola's former side Barcelona as they eased to a 2-0 win on the night and a 5-1 aggregate win over French champions Paris Saint Germain.

While Barcelona reached their seventh semi-final in eight seasons, for PSG it was their third successive exit at this stage.
