Paul Pogba — Juventus to Manchester United (2016) — €105 million

Paul Pogba's return to Manchester United from Juventus in 2016 for €105 million was the world record fee at the time, surpassing Gareth Bale's €100 million move. Pogba had left United for free in 2012 under Sir Alex Ferguson. He won the EFL Cup and Europa League in his first season but his subsequent five years at United were marked by inconsistency, injury, and a deteriorating relationship with successive managers. He left for free in 2022 and tested positive for testosterone in 2023, receiving a four-year ban subsequently reduced to 18 months.
