Tottenham chairman Levy has previously stated the preferred option would be to remain at the club's current home and increase the capacity but Spurs have also been approached with other possibilities.

The most recent suggestion reported a 50,000-capacity stadium adjacent to the current site, although Levy has stressed that the board are still assessing all of the avenues.

"I am determined that we shall work towards a successful outcome and a project of this nature and importance cannot be hurried," Levy said.

"On a point of clarity, we have taken no decision on whether or not to expand White Hart Lane and we continue to review and keep our options open."

Spurs did not want a June deadline to hamper any negotiations and the new possibilities mean the deliberations will take longer.

The value of the land in the Tottenham area is also a problem that has led to the decision taking longer than first expected.

"The difficulties with seeking a solution to our need for increased capacity are significant," Levy added.

"They include low residual land values within the Tottenham area which in turn makes enabling development less feasible, along with a limited number of suitable alternative sites within London, all of which require land assembly."

White Hart Lane holds just over 36,000 and increasing attendances is part of Levy's vision for the club, as well as making the jump from UEFA Cup football to the Champions League.

Spurs are in Europe's second-tier competition next season and there are expected to be changes in the squad this summer in preparation for the first full season of head coach Juande Ramos.

Younes Kaboul has hardly featured under Ramos and publicly criticised his boss last week, while Pascal Chimbonda has not been included in recent squads.

Rangers defender Carlos Cuellar, who sporting director Damien Comolli would have seen while scouting Alan Hutton, has been recently reported as a possible target.

Meanwhile, former Spurs boss Martin Jol, Ramos' predecessor, has been strongly tipped to return to management with German club Hamburg.
