beIN SPORTS MATCH CENTRE: Besiktas 4-1 Olympiacos | Besiktas wins 5-2 on aggregate

Vincent Aboubakar's dismissal did not prevent 10-man Besiktas from moving into the quarter-finals of the UEFA Europa League as Ryan Babel struck twice in a 4-1 home win against Olympiacos.

Besiktas had a narrow advantage from the first leg after netting an away goal in the 1-1 draw in Greece and it soon took a further step towards the last-eight through Aboubakar.

The forward's downward header from a floated Anderson Talisca centre got the Turkish side off to a flying start and its lead was soon doubled from another right-wing cross.

Ricardo Quaresma provided the assist this time, Babel controlling before lashing in a shot through a crowd of bodies that goalkeeper Nicola Leali perhaps should have saved.

Besiktas seemed to be cruising but the visitors gave themselves hope when Tarik Elyounoussi's acrobatic volley deflected in at the near post after 31 minutes and momentum appeared to swing when Aboubakar was sent off before the interval for violent conduct after clashing with Takis Retsos.

But Olympiacos could not make its extra man count and when Babel grabbed his second of the game and Cenk Tosun scored from the bench, its bid to reach the last eight of the competition for the first time failed, with Besiktas now unbeaten in its previous eight European home games.
