One of the many good things Klopp did was to get rid of the arseholes in the squad. Sakho was the obvious example of this. By all accounts a nice enough lad, generous with his time and money when it came to community work, but a bit of an idiot, and easily led (think Gazza, but not as funny). While I was there, it was notable that there were fewer and fewer internal issues with player egos. In fact you would often hear good things about how respectful the players were to the staff - just little things like please and thank you, and always saying hello to visitors. That's not to say that they were humble on the pitch - there was a time and a place for swagger - but all of his leadership group were good pros. Someone like Osimhen coming in might get the kick up the arse he needs from his fellow squad members to sort his shit out, but he would more likely disrupt the existing harmony. Not sure about Kerkez, but Frimpong seems like a top lad and Wirtz appears humble and genuinely glad to be here. I wouldn't risk the balance by throwing a dickhead into the mix.
