Tottenham have declined to comment about reports that billionaire Jahm Najafi is set to launch a £3.1bn takeover of the club.
The Financial Times reports he is working with a consortium of investors to put together a bid for Spurs.
It added Najafi was weeks away from approaching Tottenham owner Joe Lewis and Spurs chairman Daniel Levy.
Najafi is a minority shareholder in NBA team Phoenix Suns.
Tottenham, who lost the first leg of their last-16 Champions League tie 1-0 in AC Milan on Tuesday, are fifth in the Premier League.
