Firstly xylo, I wasn't attempting to go through the details. My point was meant to be just that.... An overarching point that 20 years of success under one manager is rarely followed by another.
You are going through the nuts and bolts of why the team is failing, which is fine, and most of which I agree with, but we / I have been through that plenty of times.
But let's not try and be wise guys with the benefit of hindsight here. Mourinho and LVG had outstanding track records and I don't remember too many people objecting to their appointment at the time. Ole had his sceptics, but if you recall he got off to a flyer, and during that winning streak I think everyone and his dog said we should give him a job.
Moving on to Rangnick. I'm sure you've noticed he is a very methodical guy, and therefore (going back to expectations) it will take time for him to implement those methods, and balance what you have agreed is an unbalanced squad. It might not work out in the end! But one thing I know for sure is it's not going to take half a season. We are now on a path of damage limitation for the rest of the season (in terms if what can be achieved). So let's just get behind the lads and the manager.
