I remember Klopp getting to a CL final with Karius in goal, players like Henderson and Milner or Chamberlain in midfield, players like Firmino or even Origi.
When I say that I believe its the manager and not the players - it's because a good manager will get and only utelise the good players, improving some players whilst shifting out the rest. The manager is the biggest thing of the squad, not the players and we haven't had a single world class manager in their prime -
Moyes, Van gaal, Mourinho, Ole and Rangnick.
You look at that bunch of managers and is it really that surprising that we have been sh*t?
