David Beckham believes his move to Los Angeles Galaxy will provide him with one of the biggest challenges of his career, but says it is a "dream come true".
The former Manchester United and Real Madrid midfielder was finally unveiled as a Galaxy player after months of waiting, having agreed to join the Major League Soccer side in January.
The 32-year-old midfielder signed a five-year contract with the Galaxy in January that will pay him $32.5 million in salary.
He joined the Major League Soccer team from Real Madrid, where he showed he still can "bend it" on free kicks. Coming on strong late in the season, Beckham helped Real Madrid win the Spanish League title last month.
Beckham's play also was impressive enough for him to regain a spot on England's national team, which he formerly captained.
The England international is expected to make his first appearance for his new side in a friendly against Chelsea on 21st July and he admits he cannot wait.
Beckham, who will continue to wear the famous number 23 shirt in LA, was presented to the world's media and around 5,000 fans at the Galaxy's Home Depot Center stadium on Friday.
"In my career I have played for two of the biggest club sides in the world, Manchester United and Real Madrid. I have played for 11 years for my country and I am still playing for my country," Beckham said at a press conference shown live on Sky Sports News.
"This is one of the biggest challenges that I have ever taken on in my career. I have always looked for challenges in my career and something exciting in my life.
"To move to a different country, the other side of the world, is something that I'm looking forward to.
"I think potentially in the States soccer can be as big as it is everywhere else around the world and I'm very proud to be part of that. I am going to be part of that for the next five years and maybe a few more years after.
"I'm looking forward to starting training next week, I'm looking forward to the first game, I'm looking forward to the support that you've all shown me throughout my career, not just since I've been here in Los Angeles.
"Thank you to everybody that's made this happen, made my dream come true."
The Galaxy are currently struggling in MLS but coach Frank Yallop expects the arrival of Beckham to bring a turnaround in his side's fortunes.
Yallop said: "Well finally he's here, since we signed David in January it has been a long wait.
"I feel now that David is the last piece to the puzzle for us to really start to get our season moving in the right direction.
"We are getting a great person, a winner on and off the field, a great leader and I'm very, very excited.
"The team cannot wait to get him on the field with his boots on, with his kit on, with the Galaxy jersey on and start to win some games."
