#4 They humiliated the 2017-18 winners on multiple occasions

There's no denying that Manchester City played total football and decimated the rest of the teams to claim the EPL title in a record-breaking season.
A team that played total football ascended to the top of English football with Pep Guardiola managing to take Manchester City to another stratosphere of play-making.
Moreover, the side was regarded as invincible in the initial stages of the season until 14th January 2018; the day Liverpool broke Manchester City's invincibility and made an in-your-face statement to EPL's best side.
Goals from Oxlade-Chamberlain, Roberto Firmino, Sadio Mane, and Mohamed Salah led Liverpool to a thrilling victory over Pep Guardiola's side. This wasn't the only time a victory of this magnitude happened. Both the sides were drawn to clash in the Champions League quarterfinals.
The Reds, this time around, not only went ahead to the semi-finals but completely humiliated England's best side in both the legs.
While Liverpool, unfortunately, lost the Champions League Final to Real Madrid, the side was bestowed upon with a lot of respect and adulation due to their hard-attacking mentality.
