The Paris-born keeper has signed a season-long loan deal with Vannes Olympique Club in France’s fourth tier.
Brought up in the Paris suburb of Ivry-sur-Seine, Garissone joined the PSG youth academy in 2015 at the age of fifteen.
Three years later he signed professional terms with the club and represented the U19s during the 2018-2019 season, making five appearances in the UEFA Youth League.
The following season the young goalkeeper trained with the first team alongside Keylor Navas and Sergio Rico.
During the 2020-2021 season the Parisian "titi" was loaned to Stade Malherbe de Caen, making three appearances for the Normandy-based club in Ligue 2.
The club wishes Garissone all the best in the new challenges that await him at Vannes Olympique Club.
