Valencia won away at Real Madrid for the first time since 2008 on Saturday in an eventful game for Vinicius Junior.
The Brazilian failed to convert a penalty kick at 0-0 in the first half before scoring an equaliser in the 50th minute to cancel out Mouctar Diakhaby's opener for the visitors.
But Valencia left the Bernabeu with all three points after a stoppage-time winner scored by former Madrid youngster Hugo Duro.
Vinicius stepped up to the penalty spot in the 13th minute after Kylian Mbappe had been fouled by Cesar Tarrega.
