The multi-millionaire Manchester City and former Chelsea star has an estimated fortune of over £55m and earns £190,000-a-week.
But he said he's 'very firm' when it comes to bringing up his daughters Luna, nine, and seven-year-old Isla.
Speaking to The Times, the 36-year-old said: "I am very firm to be honest. I hate the idea of spoiling them. I hate the idea of spoilt kids. It's quite lazy in a way for parents to just buy toys.
"My kids only expect what they're given. If you give them a baby Ferrari what do they want next year?"
Although the move will mean he spends less time with his girls - both from his previous relationship with model Elen Rivas – he hopes their regular visits will make them more worldy-wise.
He added: "I'm fortunate enough with the girls that they are going to come out and have their holidays there. I hope it will be a life experience for them too. I will make it work.... I will miss them a lot. I want to make sure that when I come back nothing has changed.
"I'll do whatever it takes to make that happen. But it's my job - I have to do it and I want to do it."
The idea of his kids remaining grounded is especially important to the sports star, who has written a series of children's books, Frankie's Magic Football, which deal with the ideas of greed.
Fiancée Christine will join Frank in New York and return to the UK occasionally for work.
Frank said of Christine: "We're very close - we're not good apart. We're not the kind of couple who would live long-distance very much.
"Even after a few days away from each other we can become a bit ratty.
"The way we have been since we've been together is not [looking] past six months. I do actually look forward to the day when we don't have to live quite like that."
