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.
Besiktas, who won all three of their away games in qualifying from group G, started brightly with Vagner Love shooting just over and Ricardo Quaresma forcing Bayern keeper Sven Ulreich to save at his near post.
But Jupp Heynckes’ men had 35 shots to their opponents’ six, and are well-placed to reach the quarter-finals for a seventh year in a row when they travel to Istanbul for the second leg on 14 March.
