Amongst all of them that you have mentioned, Liverpool is the only team that is look better by comparison with all that others are struggling with currently. The challenge Liverpool may be having may fall around their performance in the champions league because Slot isn't that experienced with the champions league so he may lack the technicality to handle some of the stages of the UCL but then he's still got a chance currently much more than his counterparts.
Liverpool is showing that it is the Best prepared team in the world, because they are doing excellent in their PL, despite having lost to some Teams that I didn't think they would, and also drawing with other teams that are doing very badly, but as it is part of the History of each game where anything can happen, I understand it. However, these things are valid in football , but Liverpool still has things clear, if they continue as they are they can make the UCL, and also the PL, but it is something that has to be analyzed closely because any further carelessness will mean there will be no opportunity.
