Porto players have no doubts about the quality of Eder Militao.

The Brazilian defender is the subject of intense interest from Real Madrid.

And a Porto locker room source told AS: "He's a crack, a brutal footballer, he's class, and if he signs for Madrid, he can be one of the best centre-backs in the club's history.

"When he plays as a wing-back, he is not a centre-back playing on the side, he is a pure side, that is, he is very offensive and dynamic."
