Listen, nobody's saying they ain't a quality side, but in my opinion even on their best day they simply won't be able to cope with the pressure of this latter stages, especially as long as they have such a leaky defence and overall lack of experience at this level(having many young players), could you realistically see them able to qualify over two legs against any of Bayern, Madrid, Barcelona or even Juventus atm? At this specific moment in time, this type of teams feed on your smallest of mistakes, hit you where it hurts and never look back for a moment, mentality wise we already talking about totally different calibers...
Point here would be this, is Liverpool really a UCL favorite/contender this season? 99% of the people i know will most likely tell you that's impossible atm.
