Dortmund thump Leverkusen to spoil Alonso's home farewell

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. Alonso told reporters his exit was "emotional and this club will stay in my heart forever", adding he would "forget the result from today pretty quickly".
