Former Portsmouth and AC Milan star Kevin Prince Boateng then extended Las Palmas' lead to stun the Bernabeu into silence.
However, after Gareth Bale was dismissed for shoving Viera, Ronaldo intervened to spare Real's blushes.

And Ronaldo struck again three minutes later, heading home to secure a draw.
The result means Barcelona top the table by one point but Madrid have a game in hand on their fiercest rivals.
