Former Real Madrid coach Bernd Schuster has Spanish football buzzing after an interview this week on Onda Cero.

Schuster took time out to praise Real's Spanish youngsters, Alvaro Morata, Isco and Marco Asensio - but also left fans hanging over a barb he fired at the end.

"These guys have their head screwed on straight," the German reflected.

"The madman is gone, the one who believed he was a combination of (Diego) Maradona and Cristiano (Ronaldo)."

Schuster also hinted Morata will be frustrated seeing the close relationship between Karim Benzema and coach Zinedine Zidane.

"When you come back from Juve, you think you're coming back for something, but you see his uncle, coaching and how he is ... and it is a warning."
