Cristiano Ronaldo: Real Madrid's highest scorer against Athletic
He has hit the net against the Basques in each of his seasons at the Whites, scoring 14 times.
Real Madrid are the first team to reach this figure from the sides in Spain, England, Germany, Italy, Portugal and France.
With 13 matchdays to play, he has hit more goals than the top scorers in 66 seasons of the Spanish top flight.
They will vist Rayo on Wednesday 8 at 10pm CET, and will face Éibar at home on Saturday 11 at 4pm CET.
Cristiano Ronaldo, Pepe and Carvajal worked with the rest of the group with two days to go until the La Liga clash with Athletic.
The Whites are enjoying the best away goals-per-game average in La Liga in their history: 39 in 13 (three per match).
“Winning an away game would mean strengthening our chances of reaching the quarters”, said Ayón.
