Reports have come out and revealed that Real Madrid will make the likes of Liverpool wait for the chance to sign up Isco.
Real have spent over £80million this summer on World Cup stars Toni Kroos and James Rodriguez.
That has led to talk that the likes of Isco will be shipped out, as there is no longer a place for him in the side.
But Perez claims Real may play a waiting game over any sales, like they did last summer with Mesut Ozil’s late £42.5m move to Arsenal.
As quoted on the Daily Express website, he said: “What’s important is for the season to go smoothly and for us to remain calm.
“We will start out full of hope and enthusiasm, as we and the other clubs always do.
“We all want to get stronger and there is room for improvement. We have to be in a position to challenge when the action gets underway.
“There’s always a chance of something happening up to the last day, in terms of both signings and sales.”
