The mere fact that you think not having won any trophies precludes a coach from being great, ignorantly sidestepping the CL final they reached or the progressive improvement of Liverpool during his 3 1/2 seasons, or the fact that no one has beaten Pep more than Klopp or perhaps that he hasn't actually been coaching in England for 4 years yet?
Hate Liverpool for any variety of reasons but don't spin it that they are not a great team or that Klopp isn't largely responsible for it
How the hell can they be a "great" team if they've not won anything? City won the league with 100 points plus a cup and people were lining up to say that didn't make them a great team.
