Ousseynou Ba (born 11 November 1995) is a Senegalese professional footballer who plays as a centre-back for İstanbul Başakşehir.
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 Gazélec Ajaccio in June 2017.[2] He made his professional debut for Gazélec Ajaccio in a 1–1 tie with FC Valenciennes on 28 July 2017.[3]
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.[4] His first appearance came against Lamia on 28 September 2019.[5] During the 2019–20 season, Avraam Papadopoulos’ injuries along with those of Rúben Semedo and Pape Abou Cissé 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.[6]
On 29 August 2023, Ba joined Süper Lig club Başakşehir on a season-long loan deal with the option to make the transfer permanent.[7]
On 8 March 2020, the 25-year-old central defender was called to the Senegal national team for the first time in his career. Within six months, the African has managed to win a place in Olympiacos squad, play in the Europa League and called for the two upcoming matches for the 2020 African Cup Qualifiers, against Guinea Bissau on 28 and 31 March.[8] He first represented the Senegal national team in a friendly 3-1 loss to Morocco on 9 October 2020.[9]
