I also think the politics of the job at Real Madrid might be too much for him. Sometimes it's better not say too much at those Bernabeu press conferences and Klopp might have a hard time with that. Don't get me started on what his relationship to Spanish refs would turn out to be.Yes, definitely a compelling reason. He is a long project coach, requiring loyalty and patience. I imagine he is in the right place.
On another note, I love the sight of Sheriff Tiraspol leading their group by goal difference. What a story. I reckon travelling to Tiraspol will not be fun for anyone.
