The French club ended Pochettino's 18-month tenure, during which he won his first trophies as a manager: the Ligue 1 title last season and, before that, the 2020-21 Coupe de France and 2020 Trophée des Champions.
Galtier on the other hand has left his job at Nice after one season to take the post and is due to inherit a squad that includes Kylian Mbappé, Lionel Messi and Neymar. Mbappé caused surprised in May by rejecting Madrid to sign a new contract.
Galtier led Nice to fifth place after three and a half years at Lille, where he lifted the club clear of relegation, finished second in his first full season, fourth a year later and then won the title before resigning. It was Lille’s first Ligue 1 triumph in 10 years.
