Until the 1990s, when the tide turned, under the influence of the Haiser and Hillsborough tragedies, Liverpool began to decline, and one dynasty perished, while Manchester United began a new era belonging to them, with the' 92 Golden Generation, which we are familiar with. Although they can't be the king in Europe for a long time, they stand out in the Premier League, and no team can shake their position. The top league titles they won approached Liverpool step by step (Manchester United won the 20th league title with 20 15, which has surpassed Liverpool's 18 league titles), so Liverpool no longer took them seriously, and fans of both sides began to attack each other and hate each other. Every match between the two teams is a great attraction to British fans and even fans around the world, and the relationship between the two sides has had a subtle chemical reaction.
