Robbie's LA jackpot
Ireland star signs lucrative deal to join Beckham's Galaxy
The 31-year-old will earn over £50,000 a week with his new employers after spurning an offer from Leicester to stay in England.
Keane is understood to have agreed a deal to keep him at Galaxy until the end of 2013, with his $4.5m salary making him the fourth highest-paid footballer in America behind fellow thirty-somethings David Beckham, Thierry Henry and Rafael Marquez.
He is determined to emulate Beckham and Landon Donovan by returning to Europe on loan for a couple of months at the beginning of January -- the US season runs from March to November -- but his new employers have reservations.
Spurs were keen to move Keane on as he had just a year left on his contract, and LA Galaxy and Leicester were the only clubs to come in with firm offers around the £3m mark.
"I have always wanted to come and play in the MLS so it's the perfect combination for me and a dream come true," said Keane, who must secure a visa before making the journey to California.
"When David Beckham came and trained at Spurs recently, he couldn't speak highly enough about the Galaxy, their fans, and the league in general, so I can't wait to get over and get started."
Galaxy coach Bruce Arena is delighted with the acquisition. "I believe that he brings qualities in and around the penalty area that we have been lacking," he said.
