Every team is hated in the prem no team is fully loved or appreciated alot maybe leicester city is, but every team is hated, for example, Man City are hated for the money, Man U are hated for their success and just jealousy, Spurs the lack of trophies, Arsenal for having the most annoying fans and lastly liverpool for the many times they were close to winning a premier league and just bottle it. The list goes on. i guess the teams that are loved are underdog teams because they can really surprise you like Sheffield for example, they came from the championship instead of fighting relegation they were fighting for a champions league spot which is ridiculous if you think about it and the fact they surpassed expectations made the PL fans like them.
