Alexis Sanchez wanted to leave Manchester United following his first training session after an agreement with Manchester City failed to come to fruition.
City were expected to sign Sanchez in January 2018 but he ended up joining their rivals United from Arsenal in a swap deal that sent Henrikh Mkhitaryan in the opposite direction.
The Chile international, who was reportedly being paid £390,000 per week, failed to find the form he displayed at Arsenal, where he had become one of the Premier League's leading attackers.
He scored just five goals in 45 appearances in all competitions before spending the 2019-20 season on loan at Inter, who signed him permanently last month.
Injuries also limited Sanchez's impact at United, but he confirmed City had been his first choice and he did not feel comfortable with the Red Devils from the start.
