More doubts have emerged about Zidane after defeat to Real Mallorca.
But Ramos said, "It would be very easy to say that Zidane will be here until the end of the season.
"That would put an end to the speculation. The talk of coaches who could come to Madrid is already very old.
"Everyone knows that we will give everything for this shirt under Zidane. And wherever happens we will show we are a united team, and have trust in the training methods.
"Zidane isn't frightened of anything, he knows the club and how it works day-to-day. Everything depends on results. He deserves respect for everything he has done for Real Madrid."
