Other clubs in Ligue 1 are broke, and don't have money to get the quality of players that can strengthen their teams to be able to match with PSG squad. This is the main reason why PSG has been dominating for a while and will continue dominating. This is why the league isn't that competitive like other big leagues.
This is very true and until other teams have good management that could cater for them to get best players, they will not be able to challenge them for the league title. Several years ago, it was not PSG that is the best team in the Ligue 1 but after it was taken over by wealthy Qatar company, everything about them changed and made them became the best team in the Ligue 1 and also showing great performance in the European competition they participated in. They don’t look like a team that their standard will be matched by any team in Ligue 1 now.
