#5 History and Success
Yet another criterion for comparison where City stand no chance, United are the most successful club in English history. Even after the wane of the glory years of Ferguson, United have quietly continued to pick up trophies – FA Cup under Van Gaal, League Cup under Mourinho and a healthy position for an upcoming Europa triumph.
And in case you consider it worth noting, United was founded two years prior to City too (1878 and 1880 respectively).
With 20 First Division titles and 3 European Cups as opposed to four First Division titles and no European Cups, City have a lot of catching up to do. While in the process, as Guardiola recently admitted, they would be better off focusing on step by step improvement - rather than being burdened by the inescapable glory of their rivals.
