Pochettino was linked with the Manchester United job earlier this year. It was thought the Red Devils were picking between him and Erik ten Hag, but ultimately went for the Dutchman.
Zinedine Zidane has been strongly linked with the PSG job. However, it will be Galtier who takes over.
Galtier left his job at Nice last week and was swiftly replaced by Lucien Favre. The Frenchman previously had eight years in charge of Saint-Etienne and four campaigns at Lille.
Nice finished fifth in Galtier’s only season in charge and has seemingly impressed the PSG hierarchy with his performance. The 55-year-old will inherit a squad which still contains Kylian Mbappe after the France superstar penned a new contract earlier this summer despite strong interest from Real Madrid.
