Finance affects many things in football because with money clubs can buy the players they need so that the competition will be much more interesting. Now what is happening in Ligue 1 is that only PSG has good financial capabilities so they can recruit the players they need and it is difficult for other teams to compete with them if they are in a condition like now which will indeed be limited to player recruitment.
It is true and it can not only happen in Ligue 1, but in other leagues it can also be like that because the financial capabilities of a team will clearly have a big influence on getting the best players through the transfer market. And for now I also see that PSG still has greater capabilities when compared to other teams in Ligue 1 so that PSG can still target the best players in the transfer market later, while other teams may only be able to get mediocre players without any deeper consideration. Because every player who has more value, of course this has been accompanied by achievements and also a brilliant career in the past.
Finance is indeed an important factor to support the greatness of a club, such as PSG, which managed to dominate the league after they were taken over by Qatar investors, but if you look at what Marseille and Monaco have done this season with big player spending in the transfer market, we can actually say that mentality also have an important role for every team to be champions, this season PSG did not make many player transfers but in contrast to Monaco and Marseille who have spent a lot of money but they are still not able to provide fierce competition in the league, even if we look at other leagues, there are actually many teams that also have better finances but do not have the mentality to become champions.
