That performance has been analysed to death but as one pundit put it, Klopp, Guardiola and Tuchel are top managers but Manure have a former striker. The players have to accept a lot of responsibility too - they run, tackle and press less than any other team in the prem, so whilst they have some great players, they haven't got an engine.
Not sure any manager could provide a quick solution with those players, but maybe another manager wouldn't be trying to keep them all happy as Solskjaer seems to be trying to do.
