Zinedine Zidane has warned Real Madrid he will not hesitate to quit for the second time if his team selections are met with interference from above.

Reports in Spain indicate Zidane is ready to make son Luca his second-choice goalkeeper behind Thibaut Courtois next term with long-term number one Keylor Navas seemingly close to leaving.

Doubts over the younger Zidane’s readiness to fill such a role after just two LaLiga appearances in as many seasons have clouded the issue and Spanish newspaper Marca suggests Madrid’s board prefer 20-year-old Andriy Lunin, currently on loan at Leganes, as deputy to Courtois.

The level of support from Madrid’s hierarchy was raised as a factor behind Zidane senior’s shock departure at the end of last season and, having returned in March, the head coach would not shy away from making the decision again.
