Benfica whiz Joao Felix is backing Eder Militao for success with Real Madrid.
The Porto defender will move to Real Madrid this summer.
Felix told Marca: "He is a very good centre-back.
"At his age [21] he's already played with the Brazilian national team. He is a fast, technical and smart centre-back... he is always well positioned and is one of the players you like to face because it means that we are in the best teams."
