Daniel Levy has raised doubts over Tottenham Hotspur’s proposed move out of White Hart Lane with the club securing more time to confirm whether or not they will play at Wembley next season.

Telegraph Sport understands the potential delay is associated to the full cost of Tottenham’s new stadium project, which had already seen estimates significantly increase to £800million.

Tottenham had agreed to inform the Football Association whether or not they would move into Wembley for all home games next season by the end of this month.

But, following talks, it is understood the FA have granted Spurs greater flexibility over the timescale of their decision and the club appear increasingly likely to wait until April before making a final decision.

Tottenham have not ruled out informing the FA of their decision by the end of Friday if everything falls into place in time, but Levy has suggested that he and the banks need greater assurances.

The doubt is believed to centre around the cost of the project. The first estimate, some years ago, had been that Tottenham’s new stadium would cost £450m but that increased to £750m and then £800m since Levy struck an agreement for NFL fixtures to be played there.
