And the Pucela are looking at Porozo, 19, who is out of contract at Santos next month and plans to leave.
According to AS, a meeting was held on Wednesday at the Estadio José Zorrilla to discuss the possible signing of Porozo.
Already an Ecuador international, Porozo is yet to make his first team debut for Santos, but is highly rated.
Valladolid face competition for the youngster though, with newly-promoted Serie A side Benevento already making him an offer.
Serie B side Lecce and some clubs from Belgium have also been in contact.
However, Porozo’s priority is a move to Spain, which gives Valladolid an advantage.
Porozo was voted best defender at the 2019 South American U-20 Championship, which was won by Ecuador.
