Paulo Dybala has agreed to sign for Roma, but there are reports this deal includes a release clause set at €20m.
The decision surprised many, as the Giallorossi are not in the Champions League this season, but are fresh from winning the debut edition of the Europa Conference League.
Jose Mourinho convinced La Joya to join as a free agent, signing a contract worth €6m per season including add-ons and performance-related bonuses.
It is expected to run for three years with an option for a fourth campaign.
However, Calciomercato.com claim the contract also includes a release clause worth €20m that will be active from the summer of 2023.
That suggests Dybala wanted a way out in case Roma fail to qualify for the Champions League next season.
He had been expected to join Inter, who hit the brakes after bringing in Romelu Lukaku on loan from Chelsea and failing to terminate their deal with Alexis Sanchez by mutual consent.
Milan and Napoli had also shown interest, but baulked at the wage demands.
