Klopp isn't the most competitive and ambitious. He's very relaxed and that's why his personality suits underdogs the best. Barca will never be underdogs.
That is an awful summary of what Klopp is about.
Look, you don't achieve what Klopp has without being competitive or ambitious.
But I mean, at the highest echelon of managers like Pep, Mou, Fergie, etc.....Klopp isn't as insanely competitive, desperate for individual success and as much of a "serial winner" as them.
He's a lil detached from all of that and doesn't mind if people don't consider him the best. His personality suits clubs which are underdogs and the fans can get behind him.
Posters here know how much I love and rate Klopp.
