Last September, the former Real Betis midfielder made his debut for the Spanish national team and spoke to Radio during the international break, hitting out at his former coach and the treatment he had in his debut season in Madrid.
Zidane would have to explain why he didn't give me opportunities," Ceballos responded when asked if his ex-coach understood him.
"I tried to make it difficult for him by working really hard in training, but a time comes when you see that it's impossible to impress someone.
"When weeks pass and you don't feel important, it's difficult.
"There was a moment in the season , we were 15 points off the top of the league and still in the Champions League but I didn't get any playing time."
"I even hired a personal trainer in January because the intensity falls if you don't play, I wanted to be at my peak in pre-season," Ceballos admitted.
