Since 1985, Liverpool Football Club has seen the appointment of Kenny Dalglish as manager, the Hillsborough disaster, and the club's return to European competition. Liverpool won a Premier League and FA Cup double in Dalglish's first season, and won further league titles in 1987–88 and 1989–90. A crush of people at Hillsborough Stadium in April 1989 resulted in 96 deaths (memorial pictured) and led to the end of standing terraces. In 2001, Liverpool won a unique treble of trophies, and a year later finished second to Arsenal, their highest league finish in 11 years. Liverpool won the UEFA Champions League for the fifth time in Rafael Benítez's debut season in 2005, and he guided the club to another FA Cup victory in 2006. Since 2015, Jürgen Klopp has led Liverpool to consecutive Champions League finals; the 2019 win sealed a sixth Champions League title and ended a seven-year trophy drought, followed by a win in the 2019 UEFA Super Cup.

Why you should extend your general knowledge:

There are many reasons why one should or wants to extend his knowledge.
First you should consider that "general knowledge" is knowledge which a group of humans - who belong together regional, temporal or otherwise - owns. Thus, it describes a basic understanding of specific categories of knowledge.

As the English philosopher Francis Bacon said before: "Wisdom is Power" [Bacon 1597].
