Real Madrid coach Zinedine Zidane is nervous about his defensive options.

Don Balon says Zidane is now rethinking his previous stand of going with what he has for the new season.

Zidane feels Jesus Vallejo is still too green, while Raphael Varane's fitness problems is also a concern. And having lost Pepe to Besiktas this month, he feels Real are a centre-half short.

Making things even more complicated is Nacho, who has an offer on the table from Roma to leave.

Zidane is now discussing a new centre-half signing with Real president Florentino Perez. The Frenchman is prepared to take on an experienced, mid-level stopper to boost his squad options.
