When Cristiano Ronaldo joined Manchester United in 2003, he was angered in training, prompting the administration of the "Red Devils" to lay down a new rule in the training stipulation of "preventing errors in training matches."
The talented and highly skilled young man was enthusiastic, loves to trick players and provoke competitors and even his fellow coaches.
And Ronaldo, who did not provide sufficient time then, that his talent allowed him to become one of the best players in the world, the coach involved him in a match against Bolton in the Premier League, and he provided a good level, but he lost the ball repeatedly, which prompted the technical management in the "maneu" to take a decision By stopping mistakes in training, to help Ronaldo speed the ball and not lose it because he was keeping the ball more than required.
"Ronaldo experienced difficult times in training and the dressing room. He used to keep a lot of ball and not pass it, and when he does, his decision is wrong or late," said Darren Fletcher, Ronaldo's former colleague at United.
"Alex Ferguson assistant coach Walter Smith decided not to allow mistakes in the training. Before this decision, the players were making many mistakes that were angering Ronaldo and provoking his colleagues."
"After this decision, Ronaldo seemed faster, and he passed a ball from one or two touches, and Ronaldo's talent became clear, and he uses his high speed with intelligence and high skills more effectively, and all this thanks to a wise training and tactical decision."
Ronaldo - who spent six years in "Old Trafford" (2003-2009) - scored 118 goals, including 42 in one season, even though he was playing as a winger.
He also won the Ballon d'Or in 2008 as the best player in the world after leading United to the Super League and European champions.
