Former Real Madrid midfielder Clarence Seedorf can't see Vinicius Junior and Rodrygo making it with Los Merengues.
He used the examples of previous starlets during a chat on Brazilian TV.
"Everyone dreams of playing at Real Madrid and we all know that those who arrive either live or die," he said to SporTV.
"Ze Roberto was one of the best players I saw but was never played.
"Madrid are a club with very high demands, and these two players are not going to play."
As coach of Deportivo La Coruna in 2017/18, the Dutchman had another Los Blancos loanee on the books.
"This year I had a Uruguayan (Fede Valverde) under my command at Deportivo," Seedorf continued.
"He's not going to play at Madrid but if he's lucky, he'll go to a team like Porto to mature and if he doesn't do well, others will arrive to take his place."
