La Liga is definitely moving towards being a farmer's league. Tactics are extremely sterile and repetitive at this point, nothing new to bring fresh styles, EPL is way more diverse and has everything right now. More competition even. Most anticipated games like the clasico has gone downhill ever since, now that Messi left its gonna be boring as hell.
LaLiga needs to review it's financial model for sure. And selling a stake while alienating your biggest assets isn't it.
Make no mistake, Ligue1 is a fun watch but it has nowhere near the global pull or potential as LaLiga. PSG on the other hand can/are reach status of one of Europe's super clubs and one of the worlds big global fanbase.
But being Qatari owned will also affect their global followship and Messi won't effect the needle hugely as they are still only getting him past his peak.
But their league will also work against them and they will always be judged by the CL unless somehow a major investor like the Saudi's buy a second city club like Marseille, Lyon. But there still isn't a historic rivalry there and former super clubs like Marseille and St Etienne have lost atleast 2 generations unlike Barca, Madrid, Atletico.
They also got an old Beckham who didn't move the needle long term.
