That toothy smile and belly-laugh was all many fans saw and heard throughout the 2019-20 season as Jurgen Klopp pioneered Liverpool's first league title in 30 years.
Accolades flowed in. He made it back-to-back The Best FIFA Men's Coach and was also recognised as the best in the business at the more recent BBC Sports Personality of the Year awards.
Rivals envied Liverpool for having a manager so personable, relatable and charismatic. But those that were once green with envy are now looking at a man who appears irritated, out of sorts and devoid of that charm that endeared him to English football.
