Despite having signed for the Premier League champions in 2019, the right-sided player is yet to make an appearance for the English side.
Instead, the 22-year-old spent a year on loan at Real Valladolid before starting what has turned into a hugely-successful temporary period at Sporting Lisbon.
Having helped Sporting win last season's Primeira Liga title, O Jogo claims that the Spain international is now attracting attention from Real Madrid.
Providing that they have the funds available at the end of the season, Sporting are likely to take up their option to sign Porro on a permanent basis.
However, Real can realistically offer Sporting a chance to make a quick profit on a player who has also earned La Liga experience with Girona. body check tags ::
