​Long gone are the days that Jürgen Klopp practically had to beg for his very first endorsement deal as a coach — and he didn’t even get paid for it.“As the coach of Mainz, nobody wanted to sign a contract with me, the interest from sportswear manufacturers was below zero. So I thought, at least I want to wear the clothes I like best,” Klopp once said in an interview with the Tagesspiegel paper.AdvertisementAdvertisementAdvertisement“That was Nike. I thought their gear was cool. So I went there and said I didn’t want any money. Fine.

He manages to connect with people emotionally without seeming staged,” marketing expert Felix Murbach told dpa.“It’s not his fame that makes him so valuable to brands, but the trust he has built up over many years.”Klopp’s adviser Marc Kosicke once told Die Welt that it was never the original goal “to build Jürgen Klopp into a brand” but that “it’s about the work you’ve done and the personality you have. Sporting success is the foundation for successful marketing.”AdvertisementAdvertisementAdvertisementThe DFB can certainly benefit from that as well as with Klopp as its figurehead sponsorship ne
