VIDEO: Pepe's bullet header puts Real Madrid in front in El Clasico

Real Madrid has pulled in front through the most unlikely of goalscorers. 

Barcelona once again look vulnerable defending crosses into the area, and this time they were made to pay for it by, of all people, Pepe.

Gareth Bale, missing the match with a calf injury, enjoyed the Portuguese defender's first-ever goal in El Clasico.
