Former AC Milan and Brazil goalkeeper Nelson Dida has no doubts about the quality of Roma's Alisson Becker.
But Dida says Alisson must stay grounded over the interest of Real Madrid.
He told Sportmediaset: "He is an excellent goalkeeper and he is doing very well. Already at Internacional one could see his great technical skills and now he also demonstrates it in Rome.
"After a year on the bench behind (Wojciech) Szczesny, he gained his place. He was able to wear the national team jersey with excellent performances and is now a pillar. He is growing day by day and can still progress a lot.
"Go to Real Madrid? Now he must feel comfortable and not think about the transfer window. He knows what to do and what is best for his future."
