Cristiano Ronaldo's avoidable gestures will never stop. This is how the Portuguese player is. He is so competitive that he gets frustrated and angry when Benítez calls off one of his goals during a training session. Ronaldo was caught saying "Vai caralho (come on, f***!), you only see mistakes from us the Portuguese!", as can be seen here.
Later on, during an exercise in which the players had to hit the crossbar before ending the training session, Ronaldo said "the ball should go on the net, not this s***".
This is not something smart from Cristiano Ronaldo. The Portuguese is now arguably the second leader of this team after the departure of Iker Casillas and Ronaldo must acknowledge that the press will always try to sell a bad relationship between him and his new coach.
This is probably meaningless, but Cristiano Ronaldo should have definitely been smarter and he will need to work on that this season.
