<p><br /> Jose Mourinho said he was prepared for a "big challenge" after being unveiled as Real Madrid's new coach on Monday.<br /> </p><p><br /> The Portuguese signed a four-year contract with the Spanish giants following his move from European champions Inter Milan.<br /> </p><p><br /> "I like to give myself a challenge and this is a big one," Mourinho told a news conference at the Bernabeu Stadium. "I have a lot of confidence in myself and my ability as a coach.<br /> </p><p><br /> "I want to thank the board for hiring me and I promise I will not change. I am Jose Mourinho and I arrive here with all my qualities and my defects," Mourinho added.<br /> </p><p><br /> The 47-year-old, former manager of Porto and Chelsea, replaces Manuel Pellegrini who was sacked last week, becoming Real president Florentino Perez's eighth coach in seven years.<br /> </p><p><br /> Pellegrini and coaches before him have complained about being isolated from decision-making at the club but Mourinho played down suggestions that he had demanded a greater say.<br /> </p><p><br /> "I am a coach and nothing more," he said. "It's too early to speak about changes. I have to analyse the situation, ask many questions, listen to the answers, and then decide on a way forward."<br /> </p>
