Mamadou Kaly Sène

Mamadou Kaly Sène (born 28 May 2001) is a Senegalese footballer who plays as a striker for Swiss Super League team Young Boys.

Club career Youth career Sène started his youth football with local club Vanchiglia 2014 in Turin. In the summer of 2018, he was signed by Juventus to play for their Primavera Squad, in the highest level of Italian youth football. He was with them for two seasons, playing 31 games and scoring ten goals. He also represented the club in the UEFA Youth League.

Basel On 21 August 2020 Basel announced that they had signed Sène and at the same time they also stated that, so as the 19-year-old could get match practice at the highest level, as quickly as possible, the club loaned him out to Omonia in Nicosia for a year until the summer of 2021. Because he had played 16 competitive games across all competitions by the winter break, his person met all the requirements for a Swiss work permit. Therefore, he returned to Switzerland and was able to train and play games with the Basel first team and with immediate effect.

Sène played his domestic league debut for his new club in the away game in the Letzigrund on 14 February 2021. He was substituted in the 72nd minute as Basel were defeated 0–2 by Zürich. In his first season with his new club Sène played a total of six games (five in the league, 1 test match) for Basel without scoring a goal.

Loan to Grasshoppers On 1 September 2021, he joined Grasshoppers on a year-long loan with an option to buy. In his second game for Grasshoppers on 26 September 2021, he scored twice in a 3–1 win over Sion, and a week later he again scored twice against St. Gallen. St. Gallen would prove his favorite opponent, as he scored a hattrick against them on 5 December 2021 in their second matchup of the season. In particular, his second goal in that game, a stunning overhead kick, was voted by Grasshopper fans as the goal of the season. Grasshopper chose not to take the buy option and Sène returned to Basel at the end of the season.

Return to Basel and Belgian Interest Following his return to Basel, he went to trial at Anderlecht, who would be paying a reported €2.5 million. Later on, reports linked him with fellow Belgian First Division A side OHL. However, a latent adductor injury discovered during his medical check made OHL pull out of the deal and reportedly caused Basel to consider taking legal action against Grasshoppers. Basel alleged that Grasshoppers had utilized the player while still injured. In an official statement, Grasshoppers refuted any wrong-doing, countering that Basel had deployed the forward in a test game that summer and had thus seen him as being fit enough.

He remained at Basel for the 2022–23 season. In only nine appearances across all competitions, he supplied one assist in 0–2 away victory over Luzern.

Lausanne-Sport Following the expiration of his contract at Basel, he joined Lausanne-Sport on 23 June 2023, who were freshly promoted to the Swiss Super League. He signs a three-year contract with Lausanne-Sport, where he will wear number 9.

Middlesbrough On 29 August 2025, he joined Middlesbrough in the EFL Championship on a four-year contract. He transferred for a reported 1.5m. Prior to this move, he had already scored six goals in the new season, three each in the league and the Conference League qualifying.

Young Boys On 8 August 2026, Sène returned to Switzerland and signed a four-year contract with Young Boys.
