I've been seeing lots of adverts on telly for Trivago. And these adverts bizarrely feature Jurgen Klopp. Who I expect nearly nobody in the US would know or recognize. What a strange choice of "celebrity". You'd think they'd at least use someone more recognizable to a US audience. Clearly it'a German advert, from a German company, that doesn't work on a North American audience. And Klopp's brightly bleached white teeth do not help matters.
