If you don't understand, ask, which of the Manchester Derby and the Premier League Double Red Club is more feuding?
It must be the "Premier League Double Red"!
For Manchester United, Manchester City is only a "city opponent", while Liverpool belongs to the "centennial enemy", and the two are not the same relationship at all.
For example, for Inter Milan, AC Milan is only a rival in the same city, and the centennial sworn enemy is Juventus.
Only when there are too many enmity and resentment between the two sides will they become the mortal enemies of the "worldly hatred" level.

Back to the point, let's talk about the conflict between the Premier League, Manchester United and Manchester City, more because both sides are in the Manchester area, nothing more.
The peak of these two teams is almost completely staggered.
Manchester United was proud of the years of Ferguson, Manchester City was still the Premier League "lift", they were not the big favourites to win the title, and they were once relegated.
And when Manchester City played the stage of "golden dollar football" to dominate the Premier League, Manchester United had already gone downhill.
Moreover, there are not so many ethnic, class, political or religious contradictions between Manchester United and Manchester City, and although the two sides are rivals in the same city, they have not yet risen to the height of feud.
In contrast, the feud between Manchester United and Liverpool is more complicated.
In 1895, Liverpool beat Manchester United 7-1, and the two sides began to tie the knot.
The competition between the two sides is not only because of the number of league champions or Champions League champions, but also because of the competition between the two regions.
After all, in the period of the Industrial Revolution, manchester United and Liverpool are two regions that are not on the right side with each other, we can even say that there is a regional contradiction first, and then there is a football contradiction, and the regional contradiction and the resource dispute are the causes, and the football contradictions are only the results. These are things that the Manchester derby does not have.
Therefore, Liverpool and Manchester United can be regarded as the feuds of English football.
Which team do you think is greater, Manchester United or Liverpool? Welcome to discuss together.
