Klopp, the German, had just taken over as Liverpool's head coach last October.
Standing over 1.9 meters tall, with a full beard, he wore black-framed glasses and squinted as he fixed his gaze on the two Manchester City defensive midfielders on the pitch: Tang Long and Gundogan.
"What kind of play is this?"
Before this match, Klopp had prepared an elaborate tactical plan.
He had thoroughly reviewed all of Manchester City's starting lineups since the start of this Premier League season.
Tang Long had played as a defensive midfielder before, although he mostly played as an attacking midfielder.
And his German compatriot, Gundogan, had performed well in the last game as a defensive midfielder; continuing in that role was understandable.
What Klopp couldn't understand was that Yaya Toure, who had played as a defensive midfielder for years, had been pushed to the attacking midfielder position because of Tang Long and Gundogan's presence.
"Whoa!"
