The lens could have a closer race with PSG because this season PSG was not in a good mood at all and they had too much bad atmoshpire in this team I think if Lens wants to have better performance in the next season they mnusty invest much more for their team.
I also hope so and want to see Lens' performance next season much better than this season, but the real concern lies in consistency and most clubs that manage to finish in Runner-up will find it difficult to maintain it in the following season, especially because Lens is not one of the clubs that often finishing in the top four in the League and the luck factor this season may not be repeated next season. If they don't carry out a major overhaul by bringing in several new players it will be difficult to maintain a position like this season and Lens will also play in the Champions League next season.
PSG are in a state of insecurity and many of their current stars want to leave the club, but if you look at their financial capabilities it shouldn't be a big problem. Jose Mourinho is reportedly going to accept an offer to coach PSG although until now there has been no further clarity, they have also brought in several new players and I am sure they will be looking for other players to replace some of their departed stars.
First, PSG this season continues to have good performance but unfortunately, after PSG was eliminated from the Champions League it had a bad impact on PSG's performance in Ligue 1 as well. Thus, the teams whose position is below PSG can make the distance closer, but for me personally, PSG's performance is still fairly normal, meaning it's not as bad as imagined.
Second, about Lens who managed to finish in second place or become runner up. I personally think it is purely from their hard work that managed to improve their performance and quality this season. Because, rival teams such as Marseille, Lille and Monaco are also still playing with good quality but the great thing about Lens is that Lens has been able to earn points more consistently so far this season than competing teams. Therefore, Lens' success in being able to finish with a close gap to PSG is not because PSG is weak, but Lens is able to improve their quality and performance.
Third, regarding Mourinho, I got a source who said that AS Roma really wanted to extend Mourinho's contract. If that happens, then of course Mourinho will not go to PSG because it looks like AS Roma and Mourinho have a chemistry that will probably last for the next few seasons.
