Liverpool have proved themselves the Premier League's irresistible force in the past 18 months, and we're about to find out whether Tottenham Hotspur can become the immovable object at the top of the table this season.
Reds boss Jurgen Klopp put it slightly differently in his Tuesday news conference, labeling Spurs a "results machine," in reference to his counterpart Jose Mourinho replacing flair with functionality as Tottenham arrive at Anfield as improbable League leaders with 12 games played. Wednesday's meeting between first and second -- separated only by goal difference -- asks the toughest question yet of the Mourinho renaissance, but could also serve as a referendum about whether last season's standard-bearers can repeat anything like the form that secured Liverpool's first top-flight title in 30 years.
