Jose Mourinho revealed his desire to challenge himself was a key factor in his decision to take over the reins at Real Madrid.
The Primera Division giants unveiled the Portuguese as their new manager today, with Mourinho taking over from Manuel Pellegrini who was sacked last week.
Mourinho, who guided Inter Milan to Champions League glory at the Bernabeu just nine days ago as part of an historic treble for the Italian club, has set himself the target of ending Madrid's "frustrations" at their lack of success in recent seasons.
"I don't know if I was born to coach Real Madrid but I was born to be a football coach. I love important challenges," said Mourinho, who has signed a four-year contract at the Bernabeu. "I am Jose Mourinho and I don't change. I arrive with all my qualities and my defects. My attraction to Real Madrid is due to its history, its frustrations in recent years and its expectations to win.
"It's a unique club and I believe that not to coach Real leaves a void in a coach's career. Luckily, I've had a beautiful career and it makes me proud to have come here. I am very enthusiastic. I want my players to think that way. The beauty is not so much to train or play at Real, but to win at Real Madrid," he said.
Under Pellegrini, Madrid lost out to Barcelona in the title race and were knocked of the Champions League by Lyon in the first knockout stage last season, and Mourinho believes his predecessor was affected by the constant rumours regarding his future.
"I think a coach needs to be ready to be sacked," Mourinho said. "But if a coach fears that, he doesn't work well and has great problems. I am a coach that has a lot of self-esteem and confidence and I don't think about the possibility of being sacked. I think four years of contract is enough to win, to build a strong team for the present and the future.
"The sacking of Pellegrini doesn't make me happy. I am never happy when a coach is sacked. But football is like that. I have a lot of confidence in my players, I have the hope that my new players have confidence in me," he said.
The former Porto and Chelsea boss shed little light on what changes he will bring to Madrid, but did outline his vision for the future. "It's too early to speak about changes. I believe it's time to analyse the situation, to get to know my club, ask lots of questions and get answers," he said. "I need to realise the direction of my work. The most important thing is not the coach or the players but the club.
"We are too small compared to the dimension of the club. If we work as a group, it's not difficult to get results. I want this group to have an identity, to win everything. The strength of my team is always the team and not the individuals," he continued.
The 47-year-old, who becomes Madrid's ninth coach in just six years, ended his contract with Inter last week after two seasons, with Madrid paying the San Siro club a reported eight million euros (£6.8million) in compensation.
Madrid's sporting director, Jorge Valdano, believes the appointment of Mourinho is "the best thing for the club".
"It's an honour to have with us one of the most prestigious coaches in the world," he said. "We are delighted to have him here with us. The best thing for our club right now is to have Mourinho with us."
