Inter Milan legend Marco Materazzi has jumped to the defence of nemesis Zinedine Zidane over his coaching ban.
Materazzi, who is currently working in the Hero Indian Super League as coach of Chennaiyin, says Zizou does not need qualifications to coach Real Madrid Castilla.
"When you're a champion like Zidane, myself or someone like that, you don't need a licence to coach.
"If you have a 25-year career under your belt, you should not need a certificate," said Materazzi.
Zidane's three month ban has been suspended by the Spanish courts and he was in charge for victory over Rayo Vallecano B on the weekend.
