Real Madrid director Emilio Butragueno has warned his team not to take Real Murcia lightly after drawing the third division club in the Copa del Rey.
Madrid suffered one of the biggest humiliations in their illustrious history last season after being dumped out at the same fourth-round stage by another third tier side Alcorcon, who won the first leg 4-0 at home en route to a 4-1 aggregate victory.
Butragueno warned: "Madrid have to be very alert. We've had very bad experiences in other years. It's not a competition that has given us much joy."
