But in the future, I sure there will be quite significant differences, including the development of every other team will definitely be much better and PSG dominance will decrease slightly because they certainly won't have truly perfect performance like before.
Belief that Ligue 1 can get better can also be proven by several team that previously performed poorly, now showing their performance is capable of developing with big changes.
League One will become competitive only when other clubs have access to the kind of funds PSG has. Other clubs are not buoyant enough to buy quality players like PSG. However, we cannot rule out that a club might be lucky to have the right coach and some committed players who can give PSG a good chase for the League trophy. An example is what happened in the Bundesliga last season when Xabi Alonso used a set of unknown players and made history. Bayern Munich had better players and training staff but Bayer Leverkusen was fortunate to win the title last season.
Other team in Ligue 1 can have sufficient funds if they can find investors who are willing to provide large amounts of money, several team are already owned by Saudi billionaires and those Ligue 1 team can offer to own them.
Yes, it cannot be denied that PSG has huge finances and can bring in several great players with large expenditures of money, this makes PSG team capable of dominating the league.
But at least for now the conditions are little different, I sure Ligue 1 will have better competition in the next season and we can see how each team tries to surpass PSG which is not in the same condition as before.
So that must be the motivation for all Ligue 1 teams to be able to develop team with all the players they have, there must be sense of enthusiasm in making it happen because solid team will be difficult to beat.
But everything also lies in the performance of the coach, if the coaches of several team are able to work well then it is possible that Ligue 1 will have surprises like last season Bundesliga.
