Ramos' contract is one of the biggest talking points at Real Madrid, with the centre-back not yet reaching an agreement with the club ahead of his current deal's expiry date of June 30.
Zidane has been asked about this situation many times and it was brought up again in Sunday's press conference.
"You always ask me the same thing, it's impressive man," he replied.
"I'll repeat myself and say I want it to be resolved.
"But, we have a match tomorrow and we're thinking about that."
