Liverpool manager Jurgen Klopp was known to display a fiery temper on the touchline during his time at Borussia Dortmund. According to Louise Taylor of the Guardian, Klopp's passion nearly got him in trouble with local authorities at the Stadium of Light on Wednesday.
Following a tackle by Jeremain Lens on Mamadou Sakho in the first half of Liverpool's 1-0 victory, Klopp got into an argument with Sunderland manager Sam Allardyce. Taylor reported the verbal sparring match escalated to the extent a nearby police officer told Klopp he needed to calm down.
