Tottenham chairman Daniel Levy says Spurs could be tempted to move into the Olympic Stadium after it has been used for the 2012 London Games.
Levy has been encouraged by loyalty of club's fan base
The 70,000-plus stadium to be built in Stratford, east London, would provide Spurs with an extra 34,000 seats.
"That is a possibility," Levy told The Times newspaper. "At the moment it is going to be used for athletics.
"If that changes, then I'm sure they'll come and talk to us. There are only one or two clubs who could occupy it."
Levy added: "We have the fourth largest supporter base of any English club and that is an independent assessment.
"And we are one of the few clubs that have sold every single seat this season.
"Chelsea had empty seats in the Champions League. I can tell you now that, if we were playing in Europe, I don't care who it would be against, this stadium would be full. The supporter base is not just large, it is very loyal."
