Tottenham chairman Daniel Levy has suggested the club could continue playing at White Hart Lane next season.
Spurs have until Friday to activate their option to play at Wembley.
In a statement, Levy said: "We continue to focus on ensuring that the future of the club is protected at all times.
"Therefore, whilst everyone is eager to know if this is our last season at the Lane, we shall only make the decision to decommission our historic White Hart Lane when we have greater certainty on the delivery of the new stadium.
"Our performances on the pitch and the sight of our new stadium taking shape signifies an exciting future. As we move forward with the challenges ahead, I firmly believe that the positive outlook, unity and togetherness across the club, the team and the fans means we can look forward with optimism."
