Jose Mourinho has been unveiled as the new manager of Real Madrid after signing a four-year deal at the club. The 47-year-old replaced Chilean Manuel Pellegrini to become Real's 11th coach in the past seven years.
"I like to give myself a challenge and this is a big one," said Mourinho. "I have a lot of confidence in myself and my ability as a coach."
Sporting director Jorge Valdano said: "It's an honour to have one of the most prestigious coaches in the world."
Valdano added: "We are delighted to have him here with us. The best thing for our club right now is to have Mourinho with us."
Mourinho, once on the coaching staff at Barcelona, has moved to Spain after Real and his former club Inter Milan agreed a compensation package.
I am Jose Mourinho and I don't change - I arrive with all my qualities and my defects
The Portuguese boss won the Champions League in his final game at Inter after his side defeated Bayern Munich to complete a historic Treble, having already retained the Serie A title and defeated Roma to lift the Italian Cup.
But Mourinho explained that he felt the lure of coaching Real was too strong to resist.
"I don't know if I was born to coach Real Madrid but I was born to be a football coach," he added.
"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 and I want my players to think that way," said the Portuguese.
"The beauty is not so much to train or play at Real, but to win at Real Madrid.
"I have a lot of confidence in my players, I have the hope that my new players have confidence in me."
Mourinho's Portuguese compatriot Cristiano Ronaldo joined Real from Manchester United for £80m last summer.
And the new boss hinted that the 25-year-old will have to fit into his disciplined style of play if he is to flourish next season.
"I understand that Ronaldo is an important player for Real and for the world of football," said the new boss.
"But my players must understand that the most important thing is the club.
"Cristiano likes to win, so if he likes to win it is not difficult to persuade him the most important thing is not the coach or the players but the club.
"If we all work as a group we will get results."
I think four years of contract is enough to win, to build a strong team for the present and the future."
