I wasnt considering CL final with Klopp when saying that, but D'Antoni with Suns was more impressive acheivement IMO then Klopp with Dortmund league titles, firstly because NBA is just flat out more competetive then Bundesliga in amounts of top teams you compete with considering kind of lesser teams D'Antoni has coached. Plus his system leaves a lasting effect in those teams after he left.
Anyways, I really like Klopp and wish him success tho, dont care about D'Antoni, but the german has allways been incredibly one note in his approach, he wont ever change. Doubt his success rate will change either unless he suddenly coaching best players, and even then it will take a season or two until he stagnates because his approach is fairly easy to adapt to. I noticed that mostly in that EL final he lost to Sevilla, Sevilla had an extra gear tactically, while his Liverpool seriously was just stuck in same motion hoping it will work.
