The 22-year-old – who is yet to make an appearance for the Citizens since arriving from Girona in 2019 – is currently enjoying the second part of his two-year loan spell with Sporting.
Sporting have the option of signing Porro on a permanent deal next year, and the Portuguese giants are said to be determined to keep hold of the Spain international.
However, according to Mundo Deportivo, there is also genuine interest from Real Madrid, who want to sign a new right-back to compete with Dani Carvajal for a starting spot.
Porro is under contract at City until 2025, meaning Madrid are unlikely to sign him at a cheaper price anytime soon.
Porro has scored six goals and registered four assists in 52 appearances for Sporting in all competitions.
This term, the Spaniard has again been a key player for the Portuguese outfit, featuring on 15 occasions – including four appearances in the Champions League – contributing two goals and two assists.
In reaction to the report shared on Twitter by City Xtra, some Man City fans have been expressing their thoughts and opinions.
Why has Pep never given Pedro a chance, like seriously he never let him into the team, there might be potential he isn’t exploring https://t.co/0gIs9K5h52

He should be the competition for Walker and leave Cancelo as first choice left back
