Liverpool was dire against City and barely got out of second gear, with fans making their feelings clear - much to Dominic Szoboszlai's disappointment.Liverpool has the unenviable task of taking on Paris Saint-Germain in a two-legged Champions League quarter-final tie, and will surely need to find a level that it has rarely found this season in order to have a chance of springing a surprise against the defending champion.READ MORE: Liverpool transfer news as Barcelona may hijack bid for Mohamed Salah replacementREAD MORE: Richard Hughes is 'massive fan' of Spanish manager — and it is not Xabi AlonsoIf the Reds were to lose heavily to the French giant, it's difficult to see how Slot could keep his job going into next season, particularly if the club also misses out on Champions League qualification for next season.During the closing stages of Liverpool's loss to City over the weekend, some of the Liverpool supporters who remained in the away end at the Etihad Stadium chanted Xabi Alonso's name.The Spaniard would be many people's choice to replace Slot, and would immediately provide the kind of boost that the club clearly needs right now.Alonso has carved out a reputation as a top coach since embarking on his managerial career, most notably guiding Bayer Leverkusen to the Bundesliga crown in 2024 after going through the entire season undefeated.Arne Slot is under mounting pressure at Liverpool(Image: Getty Images)That was the same year that Jurgen Klopp left Liverpool, and many expected Alonso to be the man who would replace Klopp at Anfield, but the Spaniard vowed to remain at Leverkusen for another year.That led to Liverpool appointing Slot instead, while Alonso ended up joining Real Madrid a year later – although that stint was short-lived, as he was fired after just a few months in charge.Still, Alonso's reputation remains in tact – he was just the wrong fit for a club like Madrid, which usually achieves its best results with a statesman-like manager rather than a head coach.Alonso had a win percentage of more than 70 per cent while at Madrid, so he was hardly performing disastrously, but Madrid is a unique club that requires a unique set of skills.READ MORE: Arne Slot firing agreement reached as Liverpool fans make their feelings clearOne thing Liverpool will have liked from Alonso's brief stint in the Spanish capital, though, was his adaptability with the team's formation.A concern from Alonso's Leverkusen days might have been that he employed a back-three, which was one of the reasons why Liverpool did not appoint Ruben Amorim – the Reds were concerned about the amount of money that would have been required in order to revamp the squad to suit Amorim's system.Alonso, though, quickly moved to a back four at Madrid after realizing that the players at his disposal were more suited to that formation.Tactically inflexible managers often come unstuck quickly in the Premier League – which is exactly what happened with Amorim – and Alonso's brief spell at Madrid should put Liverpool bosses' minds at ease over whether he has the same problem.Choose Liverpool.com as a 'Preferred Source' on Google News for quick access to the news you value.Liverpool FCXabi Alonso
