'It is a very complex situation, to have some of the best players in the world and make them believe they can progress through hard work. Even when you reach the standards that United have, there is always room for improvement.
We can do that with a lot of concentration, motivation and hard work. I believe it is all about the fine details; to be professional in all things. It is all about attitude.'
CARLOS SEES ROOM FOR IMPROVEMENT
"I see my role firstly as working within the strategic concept of the manager, he told the Daily Mail. "Secondly, I hope to improve the players and the team and make them ready to perform the best they can.
"I have done a lot of homework - not just on the club and the players but also the fans and the local culture. I don't have any problems or worries about working with such high-profile players. Since I first became a coach in 1978, I have worked with some of the best in the world - Figo, Rui Costa, Futre . . . many, many others.
"At the end of the day, you want players to respect you - whether you are right or wrong. You should be ready to win the hearts of the players through your competence, ideas and technical capability. I am confident that I will convince them that my work is not to burden them but to make them become better players.
