When Erik ten Hag strode into Old Trafford for the first time in May 2022 he declared of the success of Pep Guardiola and Jurgen Klopp in the Premier League: "Eras can come to an end." It's fair to say Ten Hag had designs on ending the duopoly himself rather than seeing Klopp bring the curtain down on his own tenure, but Friday's Anfield bombshell undoubtedly represents an opportunity for the Dutchman and a new-look Manchester United regime.
Who knows when Guardiola will follow, but having said the Club World Cup represented the closing of a chapter, he is likely to depart in the summer of 2025 at least and it's not out of the question he follows Klopp in going this summer.
Who knows how Manchester City and Liverpool will fare without the managers that have become synonymous with those clubs? City don't have to unduly worry about that just yet, but for Liverpool it is now an unwelcome challenge on the horizon.
After nine years, the emotional low of losing Klopp could be difficult to offset.
