Marbury told the New York Post that he plans to play in Italy, having visited the country in May with his wife, visiting Rome, Milan and Tuscany.
"I'm not just thinking of doing it, I'm going to do it," Marbury said, according to the Post. "My wife loved it there."
"It's like a [David] Beckham thing," he said, alluding to the English soccer star coming to America to play in Major League Soccer after years with top-flight European clubs Manchester United and Real Madrid.
"I would've played 13 years in the [NBA]," said Marbury, who writes a blog for the Post. "That's a lot. Most guys don't get to seven."
Marbury, a New York native, said he wouldn't want to play anywhere else, but isn't sure the Knicks would re-sign him at age 32 because of his knee tendinitis.
