Chelsea have a buyback option in the contract of Tammy Abraham at AS Roma.

However, the option doesn't come into effect until 2023.

For the moment, the Giallorosso have ruled out losing Abraham during this summer's transfer market.

But Roma do risk losing their centre forward in 2023, when Chelsea - according to the agreements signed a year ago - will be able to bring him back to London for a set figure.

Chelsea can re-sign their former striker for €80m at the end of next season.
