Manchester City boss Manuel Pellegrini has revealed that he changed his 'character' to become more successful in management.
Pellegrini said that as a player he had a different character to the one he has today, adding that in order to prepare to be a manager one must change a lot of things.
According to the BBC, Pellegrini, whose side will lift the Premier League title in his first season in England if City beat West Ham on Sunday, has avoided most of the controversies that were such a feature under predecessor Roberto Mancini, who was involved in high-profile clashes with both Carlos Tevez and Mario Balotelli.
Pellegrini, who began his managerial career in 1988 in his native Chile, said that in order to be a successful manager one has to understand that he is not a player and has to have another attitude with the players.
The Chilean also said that he knows how to control his nerves, adding that it is very important to control ones emotions because when one has to take decisions under emotion normally they do it the wrong way.
