Sarr made 141 appearances for Tottenham, scoring 11 goals and providing 11 assists, while also seeing his form earn him a spot in the Senegal national team.
The midfielder was a part of Senegal's 2026 World Cup squad, but didn;t start a game at the tournament after finishing the Premier League season injured.
He arrives at Juventus as part of a huge squad revamp, with former Spurs teammates Randal Kolo Muani and Guglielmo Vicario also joining alongside the likes of Kerim Alajbegovic and Jhon Lucumi.
