It's 10 years since Borussia Dortmund reached the Champions League final under Jurgen Klopp with a crack team featuring Robert Lewandowski, Mats Hummels and Ilkay Gundogan.
They were edged out 2-1 by Bayern Munich at Wembley that night and have won only two German Cups since. Yet, as Chelsea could find to their cost on Wednesday night, Dortmund are on the march again.
They boast fabulous young talent headed by Jude Bellingham and Gio Reyna, one of the largest and most passionate fan bases in Europe and are inspired by the emotional return of Sebastien Haller following treatment for a testicular tumour.
