I'd agree, but he's won leagues in Germany, you can't do that without a good defense/coaching, I'm at a loss to explain it, all I can think is his plan is to rotate to minimise injuries and improve fitness, even if it weakens the team.
Like you say, on Saturday It will be another mix of players who will look at each other like they have met on the pub car park before the game....
The worrying thing is there does not see an end to this coming, it's not like we're missing a few key players so we will improve in a few weeks.
His record in Germany is in the past and isn't reflective of how much he is struggling in the Premiership. I'm desperate for this manager to succeed, I really believed in him. But I'm losing the faith due to his constant changing of defenders and goalkeepers, his blind loyalty to Moreno, Lovren and the most ponderous midfield I've seen at Liverpool since Roy Hodgson and Christian Poulsen.
