At a rough estimate, PSG's annual wage bill is over £400m.
Allegedly, their commercial income this year is about £700m. From an article, it's claimed "the club added 11 new sponsorship partners. The overall income from this department is likely to reach €310m. This includes a recent deal with online sales platform GOAT, which will bring in €50m over three years, as the team’s sleeve sponsor. Qatar Airways is also set to become the main shirt sponsor for €60m-€70m a season."
Timing looks perfect - the new Saudi airline, PIF funded, is due to be named this year and as such will require a massive brand identity. From what I read, Saudia is actually quite small (in airline terms) and the goal from the new airline is to be a major player offering a lot more versatility, inter-region, far east, etc.
Long story short, we'll be PSG eventually. So let's not cry too much about it now, else we'll be inundated with screenshots in a few years time.....
