Real Madrid coach Carlo Ancelotti was pleased with Alvaro Rodriguez for their 1-1 draw with Atletico Madrid.
The teen struck the equaliser on the night, canceling out Jose Gimenez's opener.
And Ancelotti said: "He has shown all his quality and it is a special night for him and for us because we are beginning to realise that he will be useful in this part of the season. For next season he will be in the first team squad because he has the quality that few others have.
"For his age, he is tall, powerful and a formidable header. In this last part of the season we will evaluate if we need him, which I think we do, Castilla or both. We have to handle him well and Ral and I will discuss what to do.
"I ask him for what we needed. Height in the centre because in this type of game and having Karim, who is not a usual centre forward, putting in a player of this quality was good for us. We needed to focus more because he is formidable with his head."
