Legendary Manchester United boss Sir Alex Ferguson famously stated that his mission was to knock his club's great rivals Liverpool off their perch and he managed to do just that.
The Scottish manager won 13 Premier League titles, five FA Cups and three Champions League honours during his time with the Red Devils, and is regarded as one of the greatest of all-time.
Following Liverpool's success in their sixth Champions League title in June 2019, however, Jurgen Klopp's side have shown that they are able to challenge for the highest honours once again.
