Marcelo has handed Real Madrid coach Zinedine Zidane a further injury headache.

Marcelo was forced to leave the pitch as Real Betis beat Real Madrid due to injury.

The Brazilian pulled up with a muscle problem early in the second half and was replaced by Lucas Vazquez, with the nature and seriousness of the problem as yet unknown.

Reserve left-back Theo Hernandez is already ruled out for two weeks with a dislocated shoulder suffered at Real Sociedad on the weekend, which points to Nacho Fernandez being deployed in the role at Alaves this coming Saturday.
