Alberto Undiano Mallenco will oversee the action between Real Madrid and FC Barcelona as both sides go head to head at the Santiago Bernabéu on Saturday (kick-off 20:45 CET). The Navarra based official will replace Alejandro Hernández Hérnández who was initially designated to referee the LaLiga clash.
The Spanish FA issued a brief statement today stating that the change was due to the Canary Island official sustaining an injury but the communique failed to enter into detail as to the nature of the problem.
