The Spainish international, 24, scored against Alaves on Sunday but has been in and out the Real team this season.
He has started 14 La Liga games and has come off the bench in another nine.
It’s led to speculation he could leave the Bernabeu to get more regular football.
But Zidane said: “He’s going to stay for many years.
“Isco is a Madrid player and he’s playing phenomenally.
“You all know what I think, he’s an important player an I hope he stays.”
Spanish newspaper Marca claimed this morning Real were eyeing up a £20.5m move for Atletico Madrid full-back Theo Hernandez.
When questioned on a possible bid, Zidane said: “He’s a good player, there’s no doubt about that.
“I’m invested in working with my current players, anyone else I cannot talk about.”
