Borussia Dortmund romped to a 4-2 win at Bayer Leverkusen on Sunday, spoiling Xabi Alonso's last match in the home dugout while boosting their Champions League hopes.
The visitors came from one down as Jeremie Frimpong's early strike was cancelled out by goals from Julian Brandt, Julian Ryerson, Karim Adeyemi and Serhou Guirassy.
Alonso, who took Leverkusen to a league and cup double last year in his first full season in charge, announced his impending departure from the club on Friday, with Real Madrid the Spaniard's likely destination.
Leverkusen's title defence fizzled out with a 2-2 draw at Freiburg last Sunday, but the home fans were in a celebratory mood, one year after Alonso took them to a first league title in their 120-year history.
