While Los Blancos had envisioned the entire event revolving around the Bernabeu, Los Colchoneros have quietly struck a deal to host the Dolphins at their Metropolitano Stadium throughout the week, according to Vozpopuli. The Dolphins will train there daily and hold press conferences at the nearby Canillejas-San Blas complex, much to the frustration of Real Madrid’s leadership.
