If there was another club in the France league that spent as much money as PSG, we would know whether PSG is actually a strong team or a weak team. PSG spends a fraction of the money behind their club before but other clubs don't spend but other clubs compete well. The biggest reason behind the lack of popularity of the France league is that there are no good teams here to compete with PSG. From the beginning to the end of the season, we feel that PSG will do well in this league and beat all the other teams to become champions. However, if any team other than PSG wins the French league, it will be a matter of great joy for that team.
Actually there are 2 teams that I think are worthy of the strongest challengers of PSG such as Monaco and Marseille. Unfortunately these two teams do not have great finances like PSG. So that at any time if the two teams that I mentioned do not get great support from investors, I am sure League 1 will continue to be a boring league dominated by PSG.
Large investors are one of the biggest encouragement for the development of the team and investors certainly require proof that League 1 or the team that will be in the danged must have a slightly more consistent power. But the fact is difficult for now to bring in professional players from other teams. Because other professional players judge in League 1 will not provide a big career when seeing unattractive competition.
