What is Conte's reason to leave Spurs? He was just hired as Spurs manager the last year and has an active contract until June 2023. As a professional coach, I believe he will stay in Spurs until his contract expires. He also must be interesting to manage Spurs in the next season because he knows the big challenge to lead this team in EPL. EPL is the biggest competitive league in the world, each manager must have a dream to manage a team there. Conte won't easily give up and leave this league. By the way, Zidane has a bigger achievement than Conte, so basically Zidane is a more appropriate coach for PSG. The question is, does Zidane want to coach PSG? 
Conte currently linked to PSG even he personally offering himself as the candidate new manager of PSG so if the management of PSG choose him as the replacement of Pochettino then without doubt he will choose PSG instead of Tottenham and regarding his future in Tottenham most people predict if Tottenham failed reach to top 4 probably he will leave and also the rumour is his relationship with the club owner Daniel Levy is not very good because he doesn't like transfer players behaviour for next season from the owner
