Bayern Munich put five past 10-man Besiktas to equal their longest winning run and take a convincing lead in their Champions League last-16 tie.
The hosts won their 14th consecutive game after a dominant second half against Besiktas, who had Domagoj Vida sent off after 16 minutes.
Thomas Muller converted from close range in both halves and Kingsley Coman also swept home.
Top-scorer Robert Lewandowski added two more for Bayern as Besiktas tired.
