Xabi Alonso was presented as a Real Madrid player after signing a five-year contract at the Bernabeu.
The Basque midfielder joins Madrid from Liverpool for around Â£30million and was unveiled at the stadium on Wednesday evening.
The 27-year-old Spain international arrived in the capital earlier in the day after a fee was agreed between Liverpool and Real Madrid.
The midfielder is Madrid's eighth summer signing, taking the Primera Division giants' spending to over Â£220million in just two months.
Madrid president Florentino Perez has brought in Cristiano Ronaldo, Kaka, Raul Albiol, Esteban Granero, Arbeloa, Alvaro Negredo and Karim Benzema as he attempts to build a team capable of challenging Barcelona's treble winners.
"It's a very happy day for me," said Alonso. "It's an important step in my career to come to a club like Real Madrid.I'm very happy to be part of this club and I was very excited for this day to arrive.
"I am very grateful to Liverpool fans, they were very warm during my five years. It will be really difficult to match their appreciation and I really enjoyed those five years.
"But a few months ago I took that decision as I thought it was the right moment to find a fresh challenge, to look for a new club. That's when Real Madrid came along."
The transfer was one of the most protracted deals of the summer but Alonso claims he always believed he would be at the Bernabeu before the start of the season.
"I didn't have all the cards in my hand but I was confident," he said. "The end result was what I wished for, here I am and I am very happy."
