Celta felt Bale should've been sent off for a dangerous challenge on Rafinha.
"I saw the tackle and Bale had no chance of playing the ball, it was a tackle from behind ... Against Granada they expelled two players for less than this. Refereeing in the Santiago Bernabéu is sometimes difficult," said Celta striker Iago Aspas.
Celta defender Jeison Murillo also said, "Bale completely forgets the ball, takes him from behind, with the option of clearly injuring him. Luckily, Rafa is fine.
"It is a bad move, he totally forgets the ball, he can injure him. The referee decides. That's how it looked on the field."
