Champions Bayer Leverkusen extended their unbeaten streak as they secured a 5-1 away victory over Eintracht Frankfurt in the Bundesliga on Sunday. Manager Xabi Alonso, whose side was heavily rotated, had to watch from the stands as he served a touchline ban for yellow card accumulation, but it made no difference as Leverkusen continued their dominant form this season. The result leaves Leverkusen at the summit with 84 points, while Frankfurt sit sixth with 45.
