Hendo. I understand where you are coming from but I guess you aren't seeing my point. I don't hold anything against MickeyArmenian for picking BVB over us. Its his choice. They are in the Champs League we aren't and so on. But I think "greatness" is bandied too easily these days. BVB is a good club but not a great one. Bayern is a great club. Just like Dortmund's past transgressions have nothing to do with the present so should Liverpool's last 5 years. That was an anomaly forced on us by a couple of first grade twa*s.
He picked BVB because they are in the Champs league but to say that he picked BVB because it is a great club would be overstating it. Oh well, I guess we will agree to disagree.
Dortmund has shown an incredible sense for building and rebuilding a squad under Klopo, Watzke, etc. Lose Barrios? Lewandowski. Lose Sahin? Gundogan. Lose Kagawa? Reus. Lose Götze? Mkhitaryan. Plus they added Aubameyang who looks incredible.
Also I don't think Klopp has constantly rebuilt the BVB team he has replaced players. Rebuilding would be what Matt Busby did after Munich, what Shankly did with his first and second great Liverpool teams, or what Fergie did with his first great United team. rebuilding would be when you make wholesale changes to the squad and come up with one that looks nothing like the one you started with.
Aubameyang well thrive at BVB. Dunno why no one else went for him. Him, Adam Maher and Bruma I felt went for below their worth in the transfer market.
