The Dutch midfielder are in talks with FC Dallas, who is managed by former Arsenal midfielder Steve Morrow.
Morrow said: “We are actually in negotiations with Edgar Davids – we’ve been speaking for a couple of weeks.
“We were excited to hear about his availability, so we spoke to his agents and have been told he is available.”
He added on BBC London: “It appears Tottenham are willing to listen to offers.
“It’s the transfer window in the United States now – and if a deal is going to happen it has to be done before the end of the month.”
