The Portuguese player was mad with Los Blancos' fans recriminations when the team was trailing Rayo Vallecano on Sunday.

There's a reason why Cristiano Ronaldo did not celebrate his goals as usual against Rayo Vallecano, and apparently this was caused by his team's supporters.

After an early goal by Danilo, Los Blancos conceded a couple of goals against Rayo, which infuriated fans at Santiago Bernabéu Stadium. Things turned a bit uglier when Keylor Navas saved Los Blancos from a third goal, and in the previous moments to that corner kick, Cristiano Ronaldo recriminated Real Madrid's fans for booing the squad when they needed them the most.

Holding up his right hand, he disagreed with Los Blancos' supporters, who quickly vented their frustrations against him. Even co-captain Marcelo noticed the player's reaction and asked him to keep his act together.

A number of fans noticed CR7's gesture, and immediately directed their insults against him. "You've got some nerve", "You son of a b***h", "You're just a rock star" and many more which can't be reproduced. You can have a more detailed look at their reaction here

This is not the first time Cristiano Ronaldo argues with Real Madrid's home crowd. Back in March, the Portuguese ace was baffled by a number of fans who jeered at Los Blancos in a match against Levante. CR7 told them off using a Portuguese slang and walked away, raising huge criticism by fans and media.
