The Frenchman holds a director of football role with the Spanish club and is reportedly keen on replacing Jose Mourinho as first-team manager.

However, Remon, who managed Real Madrid for just three months in 2004, believes Zidane is not yet prepared to take up such a high-pressure role.

"To be the coach of Real Madrid requires a special responsibility," the 62-year-old told Marca.

"It's very complicated, they expect results. It is premature to say that 'Zizou' will coach Real Madrid.

"Everyone's talking about Madrid, and under this pressure, the coach still has to make important decisions. All coaches will have added pressure at Madrid, more than at any other club.

"Towards the end of long contracts, the results are evaluated. If the numbers are negative, then the deal gets terminated. We have seen an example recently with Mourinho, who had a contract (until 2016)."

Zidane made 247 appearances for Real during his playing career, scoring 48 goals and winning both La Liga and the UEFA Champions League.
