Now money in soccer is necessary and obligatory because things are changing frequently and clubs are looking for best in market which is not possible without money few clubs are having enough sources which are changing momentum of soccer.
Clubs like PSG and Manchester City had enough success due to money and their sources which used by their owners which want to win everything in their leagues just because of this mindset now difference of quality is almost had widened, and few clubs are dominating in every league, but after this few clubs are having great depth which not challengeable.

Right! Football these days is gradually being taken over by rich club owners.
