says his children love America and his wife has been warmly welcomed here.
"But on my side," he says, "it's frustrating at the moment."
A knee injury
this week will sideline the British soccer star for as long as 10 weeks, possibly ending his season with the Los Angeles Galaxy and abruptly ending the hoopla over his big arrival in America.
"Obviously, I'll be working at trying to get myself fit and trying to get myself better, and hopefully be able to maybe play before the end of the season," the athlete, 32, told Ryan Seacrest on his KIIS-FM morning show. "But the doctors are not that sure about it. It's disappointing and frustrating at the moment."
Beckham strained his knee ligaments during a fierce tackle at Wednesday night's game against CF Pachuca Superliga at L.A.'s Home Depot Center. An MRI on Thursday confirmed the injury, and the team said he would be out as long as six weeks, though Beckham put the estimate longer at eight to 10 weeks.
"I'm hopping about at the moment, which isn't great," he says.
Beckham, who had already been nursing an ankle injury, says he may have "rushed back too early."
"My ankle is not completely right, maybe 90 percent right," he told Seacrest. "I always try to play. That's the problem. Coming back and going into game not fully fit, it gives my body a chance to have other injuries."
Otherwise, life in America with wife Victoria
and three sons is generally great, though he acknowledges the spotlight has put extra pressure on the team.
"I think it's been very difficult for everyone involved," he says. "But it's also been good in a lot of ways as well. This league needs the attention. The club needs the attention. This sport needs the attention in the US. In a good way it's worked, in other ways it's not."
As for his children, they have "reacted really well" to a new country and a new school.
"It's always difficult when you got three kids and trying to get them adjusted pretty quickly," he says. "They love it here. We said it right from the word go: It's like they're moving to Disneyland. That's what they had in their heads straight away. They couldn't wait to get here. They've settled into the school."
And, he says, he and Posh Spice are looking to expand the brood.
"At some point we will. We were speaking about it the other day," he says. "We both want four or five kids and a big family."
