Fiorentina included a new contract option in Sofyan Amrabat's deal ahead of his move to Manchester United.

The midfielder has joined United on-loan for the season with an option to buy.

Amrabat's deal with Fiorentina runs to 2025, but that can be extended if United decide against buying him.

Il Tirreno reports Fiorentina included an option to Amrabat's United contract to protect his value.

The clause states that if he returns to the club at the end of the season, they can extend his deal until 2026.
