Tottenham have announced they could leave White Hart Lane for a new stadium in three years

Tottenham have announced they hope to leave White Hart Lane and move into a new 56,250 capacity stadium in 2017.

Chairman Daniel Levy has also defended a season of upheaval and promised there will not be another major overhaul to the playing squad this summer.

Levy and Spurs are waiting on the result of a public inquiry that was opened last April, which has delayed the purchase of the remaining property needed for the land to build the new stadium.

The Northumberland Park Development, which incorporates the new stadium, will cost Tottenham around £400 million.

A Spurs statement read: "In respect of the next stage of the new stadium process, a Public Inquiry was held in April 2013 relating to the last remaining property to be acquired so that we can move forward with completing land assembly and we currently await the Secretary of State's decision on the Compulsory Purchase Order. During the delay in land acquisition, we have continued to progress the stadium finance plans with advice from N M Rothschild.

"It is a major development that will present ongoing challenges and subject to these challenges being manageable we anticipate going out to tender for construction late this year, which will make a stadium opening date of summer 2017 feasible."

Levy added: "We have fantastic, strong support. Our current 36,000 seater stadium sells out and the waiting list for season ticket holders is currently in excess of 47,000.

"We cannot stress strongly enough how critical the new stadium is over the long-term to these raised expectations. We have the smallest capacity stadium of any club in the top 20 clubs in Europe, let alone the current top four Premier League clubs, and given we now operate within Uefa Financial Fair Play rules, an increased capacity stadium and associated revenues is fundamental to supporting the future ambitions and consistent achievement at the top of the game.

"Our focus, therefore, is to continue to invest in and develop the squad - we shall not look to a summer of major upheaval, but rather to strengthen in key positions - to play the style of football for which we are famous - and to deliver the new stadium."

Levy has come under fire from a section of fans this season over his decision to replace Andre Villas-Boas with head coach Tim Sherwood, the role of technical director Franco Baldini and last summer's transfer business.

A group of supporters have set-up an online petition that asks fans to: "Express your lack of confidence in ENIC and Daniel Levy's day to day management of THFC." It currently has over 1,500 signatures.

But Levy has defended his actions and the season as a whole, saying: "We are in sixth position in the Premier League and it has been another season when the top four places have been fiercely contested by at least seven teams. It is no surprise that the English Premier League is the most watched League in the world as every season the fight for a top four Uefa Champions League place becomes more competitive.

"We have come far in the last decade - we have raised our expectations from a club aiming to be in the top half of the table, to competing in Europe each season - to the point at which we find ourselves disappointed if we don't make Champions League.

"This season we have had to make significant changes, both in respect of coaching and playing staff and yet we are currently only two points less than last season's tally. Whilst this season's performances and results have not lived up to expectation, we believe our squad has potential and it is important that we all now show commitment and teamwork to get the best possible finish to the season."

Tottenham announced a profit for the year ending 30 June 2013 after tax and interest of £1.5 million, having made a £4.3 million loss in 2012.
