The talented defender has been earning rave reviews for his displays this season, and has in turn seen his name linked with some top European clubs.
A Bola understands that scouts from Borussia Dortmund and Napoli watched the young stopper at the weekend as Nacional shared spoils with Rio Ave.
Miguel Rodrigues, 19, came through the youth ranks at Fatima and Uniao Leiria, where he began his professional career.
Despite appearing in just two league matches for Leiria, Miguel Rodrigues seemed to have done enough to earn a summer move to Nacional.
He has been playing pretty well this season, making 11 Primeira Liga appearances for Os Alvinegros.
Rodrigues, who is predicted a bright future, is currently a part of Portugal Under-20 side, having made his debut in a friendly match against Slovakia earlier this year.
