It's like all the clubs in Ligue 1 have given up to PSG as their king without a rival. If not we would have seen at least one club that would have challenge PSG and make history for themselves for once. However, the poor financial condition of those clubs is something we need to put into consideration which is one of the major reason why PSG is dominating the league.

So this shows that it is also possible for these teams to build a strong squad with the financial conditions they have and then fight for the title.
