Alvaro Morata says he has nothing to prove to Real Madrid coach Zinedine Zidane.

Morata left Juventus for Real Madrid last week.

"I don't have to prove anything to Zidane," Morata stated. "It's not like I'm still a Castilla trialist.

"The coaching staff will decide if I belong at Real Madrid. I will give my best to compete for a place in their plans."
