What you say is true but he hardly works with the same budgts that he had back in the days. At Liverpool, Klopp could buy virtually any player active outside of the EPL. If he goes there, I would be thrilled by his work with their youth academy. He would easily give three, four young players their chance in the squad.
I'd be thrilled too, if Klopp joins the Kop. But with more money at Dortmund, the spendings rose, the actual quality of transfers didn't though. Even worse though was the fact that it severely hampered the development of young players, who were sold or loaned out (Leitner, Bittencourt, Ginzcek, Hofmann, Koray Günther, Sarr).
Except for Durm not a single youth player emerged in the last two years due to the fact that expensive (non-performing) players were bought.
He'd be great for us when Wernger retires,b ut I hope that's not any time soon.
I think the fact that quite a few german players are located at Arsenal right now could be detrimental. Just look at Pep and his new FC Bavario Municho. He isn't able to articulate his ideas and motivational speeches in german. But he speaks spanish with all his spanish players.
And before you know it you have cliques inside your team, people accusing him of favoring spanish players and all that shabang. Ain't nobody got time for that.
I'd rather see him at Liverpool. Especially since that team might have more potential hidden.
