Eriksen, who is out of contract this summer, has rejected several offers from Spurs in the region of £200,000 a week and can negotiate a free transfer directly with foreign clubs from January 1.
Asked whether he would sanction a sale to another Premier League club, Levy told the London Evening Standard: “We are honestly not scared to trade with our rivals."
He continued: "My view is really simple. For a player to sign a new contract, not only have the conditions got to be right but the player has got to want to do it. It is up to those players whether they want to stay at Tottenham and we'll see.
“I don't want to comment on individual players too much. I actually think it is unfair. Every circumstance is different. There may be a player who wants to stay, there may be a player we don't want to stay."
