I actually think it is a good decision to get Pochettino sacked, he clearly can't get the job done. It is quite unfortunate that players can’t be sacked easily cause Marquinhos and Kimpembe should have followed him for bottling the UEFA Champion's League this season and some home games in the ligue1 this season. I think the right fit for the job will be the likes of Ancelotti and Guardiola not Conte, Conte won't be able to handle the egos in that team for long.
Absolutely yes he has out from PSG after many failure on Champion League competition and many time stuck on domestic league although success with trophy achievement but have different level competitive on domestic league. Maybe still waiting until league ended for out Pochettino from PSG although he has several years contract. Not worry with PSG have good financial for sacked Pochettino before his contract over and looking new manager with great experience achievement like Zidane.
