I think it's well known that he's fallen out with Leonardo, the PSG board would love Zidane in charge, to the point the owners brother is posting Tweets about him being 'his manager' or whatever it was. Then you've got the state of the lunatics running the asylum over there with Messi, Neymar, Mbappe etc getting whatever the feck they want whenever they want. It really is an impossible job for anyone that isn't Zidane in my opinion, and it doesn't reflect badly on Pochettino for wanting to get the feck out before they give him the bullet.
