Madrid have until June 10 to finalise the deal before the Club World Cup roster deadline — a tournament in which Benfica will also participate. If an agreement cannot be reached in the coming days, Madrid may shift their focus to Grimaldo. The 29-year-old Spanish international has long expressed interest in joining a top-tier club, and if Carreras' move falls through, a high-profile switch to the Bernabeu could soon be within reach for the former Benfica full-back.
