"It's not out of the question," FC Tokyo official Fumitoshi Wakabayashi told Reuters. "The club is always trying to improve and (Nedved) could be one option."
"There is nothing concrete to say at this stage," Wakabayashi said. "But in truth I can't say if there's been contact made and at what level."
The 35-year-old Nedved won 91 caps for his country before retiring from international duty shortly after the 2006 World Cup. He was voted European player of the year in 2003.
"It all depends how things develop from now," FC Tokyo chairman Yutaka Murabayashi said. "But we will do everything we can (to sign Nedved)."
