Real Madrid boss Carlo Ancelotti is unhappy with comments from Rayo Vallecano rival Paco Jemez.
Jemez has slammed the appointment of Zinedine Zidane as Castilla coach without the necessary qualifications.
Ancelotti said: "It isn't easy for me to get into this issue. In a press conference, there is the danger of speaking too much.
"This coach spoke too much. Zidane has been doing a course with the French FA for two years and in other countries you can coach teams when you're doing the course. There is a different rule in Spain. Paco spoke too much."
