Four years ago today, a new era began at Liverpool Football Club as Jürgen Klopp was appointed as manager.
The German put pen to paper on his deal with the Reds on October 8, 2015 at a city centre hotel, beginning a fresh chapter in his career after successful managerial spells with Mainz and Borussia Dortmund in his homeland.
Klopp would take the helm for the first time nine days later – a goalless draw at Tottenham Hotspur – to start his Anfield tenure.
In total, the 52-year-old has presided over 221 matches as Liverpool boss, during which time his side registered a club-record 97 points in a single season and, of course, lifted the UEFA Champions League and Super Cup trophies.
