Ousseynou Ba (born 11 November 1995) is a Senegalese professional footballer who plays as a centre-back for Greek club Olympiacos.
Club Career
Ba was a youth product from the Senegalese SMASH academy, before moving to Amiens in the summer of 2016. Unable to get a work permit for them, after a year of not playing Ba managed to get a work permit when he signed with Gazelec Ajaccio on June 2017. He made his professional debut for Gazelec Ajaccio in a 1–1 tie with FC Valenciennes on 28 July 2017.
In January 2019 Ba signed with the Greek club Olympiakos for an undisclosed fee, but it is decided to play till the end of the season in Ajaccio.His first appearance came against Lamia on 28 September 2019. During the 2019-20 season, Avraam Papadopoulos’ injuries along with those of Ruben Semedo and Pape Abou Cisse suddenly brought the previously fifth-choice center-back, Ba into the side. This was the opportunity the player needed. After coming into the starting line-up in early December versus Panetolikos, Ba remained there until the season was interrupted by the COVID-19 pandemic. During that stretch, Ba played 16 matches in less than 100 days, participating as a starter in every one of those games.
