Of all factors explaining the chasm between Manchester United and Liverpool right now, not one can compare with the differing approaches to appoint their latest managers. Liverpool were compelled to hire Arne Slot after consulting a highly sophisticated data model developed by a Harvard-educated physicist. United, meanwhile, recruited Ruben Amorim largely because of the vibes.

United love a good narrative, and the way that Amorim had revived Sporting CP’s fortunes by delivering a first league title in 19 years was highly appealing to a club at a loss as to how to rise again after more than a decade of decline after Sir Alex Ferguson retired in 2013. The club’s main decision-makers, Sir Jim Ratcliffe and Omar Berrada, wanted a young charismatic coach on the rise and in Amorim they saw shades of Mikel Arteta and Pep Guardiola. 

Every time Ratcliffe has discussed Amorim, he has lauded his personality, describing the Portuguese as “intelligent” and “thoughtful” while speaking fondly of their chats over coffee at the Carrington training ground, where the co-owner tells the coach “where it’s going wrong, and he tells me to f*ck off.” 

What was lacking in United’s thought process when they hired Amorim, however, was a thorough analysis of the most intriguing thing about him: his loyalty to the 3-4-3 system. Liverpool, by contrast, saw Amorim’s formation fixation as a massive red flag and turned away from him and towards Slot.

Slot might be enduring his most difficult period as Liverpool boss as his side prepare to welcome their arch rivals to Anfield on Sunday after three successive defeats, but overall he has proved to be a brilliant hire. Quite unlike Amorim, who has created an even bigger mess than the one he inherited when he took charge of the Red Devils 11 months ago.
