I wouldn't say I really hate other teams. But clubs I don't like would be any of these nouveau riche plastic clubs like Manchester City, PSG and Chelsea. I don't actually care what they win, what they win just seems meaningless in the grand scheme of things, but they are just a symbol of much of what is wrong with football these days.
I also don't like RB Leipzig for the same reason, a plastic, manufactured club, and a stain on the league. Although I am slightly conflicted at times cos at least they do play some good football to watch as a neutral, and at least go down the route of building through very good scouting and youth rather than just spending a billion euros on ready made stars for their squads. But yeah, I don't much care for them.
