Niko Kovac stunned his future employer by leading Eintracht Frankfurt to a 3-1 win over Bayern Munich in the German Cup final on Saturday.
The Frankfurt coach, who has agreed to take over from the retiring Jupp Heynckes in Munich next season, oversaw a committed performance from his side crowned by two goals from the impressive Ante Rebic.
The Croatian striker scored early and late to cancel out Robert Lewandowski’s equalizer for Bayern.
Bayern might have had a penalty in injury time, but referee Felix Zwayer decided otherwise after consulting video replays, and Mijat Gacinovic then sealed it on a counterattack for Frankfurt.
It is Frankfurt’s first title for 30 years and also provides a ticket to the Europa League next season.
Kovac has gone one better after his side lost to Borussia Dortmund in last year’s German season-ending showpiece.
