Bayern Munich cemented their passage into Champions League history and the quarter-finals with an emphatic 7?1 victory over the hapless Sporting Lisbon . Having won the first leg 5-0 in Lisbon, Bayern piled on the humiliation for the Portuguese club to record a 12?1 aggregate win.

The most goals scored in a single European match remains 14, set in 1969 when Feyenoord defeated KR Reykjavik 12?2, but Bayern became the first club to score 12 goals over the two legs of a Champions League knockout tie. The 7?1 scoreline here also equalled Manchester United's record winning margin in a single leg of a Champions League knockout tie, set in 2007 against Roma at Old Trafford.

The final margin could have been much worse for Sporting as the defensive errors compounded. Lukas Podolski opened the Bayern account after just eight minutes with a superb left-footed strike from outside the area that left the Sporting goalkeeper Pedro Rui Patricio grasping at air.

Bayern then blew the tie away with a three-goal burst in nine minutes thanks largely to some comical defending from Sporting. Podolski added his second in the 34th minute after Patricio and defender Correa Anderson Polga ran into each other. It got worse for Anderson Polga five minutes later when he turned an innocuous cross into his own net.

Sporting finally got on to the score sheet thanks to an excellent strike by Joao Moutinho in the 40th minute. His celebrations were decidedly muted and any joy the visitors extracted was quickly numbed as another defensive lapse left Bastian Schweinsteiger unmarked in the Sporting box and with the easiest of finishes.

Teenager Thomas Muller, making his debut in European football, set up Bayern's fifth, their first of the second half, with a run down the right, his cross headed on by Miroslav Klose and volleyed home by Mark van Bommel. Klose then added a penalty after he was brought down in the box, and the 19-year-old Muller capped his debut by tapping in Bayern's seventh in the final minute in a goalmouth scramble.

Jurgen Klinsmann rested Franck Ribery and Luca Toni, who both scored twice in the victory in Portugal, along with midfielders Tim Borowski and Hamit Altintop. Sporting, too, rested key players including the club's top scorer, Liedson, who has scored 14 goals in all competitions this season.

In Athens, Villarreal sealed their passage into the quarter-finals with a 2-1 victory over Panathinaikos . The Greek club's away-goal advantage from the first leg was rubbed out early in the second half and although Panathinaikos hit back to level, substitute Joseba Llorente's 70th-minute volley put the Spanish side through.

Ariel Ibagaza had given Villarreal the goal they needed in the 49th minute, cancelling out the away goal they had conceded in the first leg. Vangelis Mantzlos headed Panathinaikos back into the game six minutes later, getting on to the end of a corner from Georgios Karagounis from six yards to beat Diego Lopez, before Llorente sealed the tie.

A scrappy first half saw little chance for either side to assert any control over the game, although Ibagaza had put the ball into the Panathinaikos net after 36 minutes, only to have the strike ruled out for a foul on defender Loukas Vidra.
