Mikel Merino's departure from Newcastle United has stalled over contract terms.
However, AS says the deal has stalled due Merino's demands of a low buyout clause.
All three LaLiga clubs want to set the option at €60m or higher, while Merino wants it to be affordable in the event a bigger club comes in for him.
La Real president Jokin Aperribay is already in England today for talks with Newcastle about a deal for the midfielder.
Newcastle are willing to sell for €15m.
