Nail, head.
Don't get me wrong I like Klippity but he could build a Dortmund team whilst at the same time offering thereabouts guaranteed CL football. Plus Germany have and still are going through a purple patch of producing national talent which don't particularly want to leave in search of riches abroad and they were the second best club in Germany.
All of that helps hugely in building a squad and Liverpool currently cannot offer any of what Dortmund did. Great youth? Nope (perhaps bar Ibe) guaranteed CL football, certainly not, one of the best teams and payers so can keep top talent? Nope.
I don't think Liverpool are in a "bad" situation and I'm not saying the above to knock Liverpool just to highlight that Klippity had a lot going in his favour to help succeed at Dortmund that he won't have at Liverpool.
Can he do it? Yea, he could. Will he do it? It's a huge IF and I certainly wouldn't be getting carried away considering City, Arsenal are nailed on and ManU/Chelski are still relatively under performing so will improve.
Regardless will be interesting!
