The left-back will be a free agent when his contract with the Spanish side runs down in June 2024 and does not seem intent on discussing an extension.
With that in mind, he could be allowed to leave in the January transfer window for a cut-price fee of €4m, although half of that would go to his previous club Barcelona.
It has been known for some time that Milan were in talks with both Miranda’s agent and the Real Betis directors, laying the groundwork for this deal.
Now Calciomercato.com suggest that Napoli are ready to make their own proposal for the 23-year-old in January.
This is considered necessary because both Mario Rui and Matheus Olivera are currently out injured, forcing Napoli to use centre-back Natan on the left side of their defence.
The Partenopei would have to also match the salary agreed with Milan, which is a five-year contract at €2m per season.
