Liverpool's 4-0 FA Cup quarterfinal defeat to Manchester City has intensified scrutiny on manager Arne Slot, with fans singing for Xabi Alonso to replace him during the match. The loss marks Liverpool's 15th defeat of the season and their heaviest under Slot, who won the Premier League title last year. Supporters began leaving Etihad Stadium with over 20 minutes remaining, highlighting the growing disillusionment.

This latest capitulation follows a troubling pattern for Liverpool, who have lost five games by three goals or more this season after not suffering a single such defeat last year. The team's lack of fighting spirit was evident, with midfielder Dominik Szoboszlai admitting the mentality wasn't there. Liverpool have won just two of 19 games when falling behind, a stark contrast to their former "mentality monsters" reputation under Jürgen Klopp.

The pressure now shifts to Wednesday's Champions League quarterfinal first leg against Paris Saint-Germain, which could determine Slot's future. While injuries and squad issues have complicated his season, the buck ultimately stops with the manager. Liverpool owners Fenway Sports Group have supported Slot throughout this turbulent campaign, but continued poor results against rivals like Everton, Manchester United, and Chelsea could make his position untenable.
