Besiktas' credentials for winning the Europa League are more than Babel.
The well-travelled Ryan Babel followed up Vincent Aboubakar's header from 12 minutes earlier by knocking the ball through a crowd and past the inadequate grasp of Olympiacos goalkeeper Nicola Leali in Thursday's last-16 second leg.
The 30-year-old added to his effort on 75 minutes as Besiktas recorded a 4-1 victory on the night and a 5-2 aggregate scoreline overall.
