The 57-year-old Greek-born tactician remained tight-lipped about his future following Celtic's Scottish Cup final triumph over Inverness on Saturday.
But football transfer expert, Fabrizio Romano said, "a two-year-deal with an option included for a further season, so potentially valid until June 2026" has been verbally agreed between Tottenham and Postecoglou.

Postecoglou guided Celtic to a domestic treble with the cup victory, marking an impressive achievement for the club.
Tottenham is exercising caution in their public statements due to the previous speculation surrounding their interest in Feyenoord's Arne Slot, who ultimately opted to remain with the Eredivisie champions.
The club is determined to avoid a repeat of the protracted saga they encountered in 2021 when they pursued multiple candidates to replace Jose Mourinho without success.
Their eventual appointment of former Wolves manager Nuno Espirito Santo ended prematurely, with his dismissal occurring after just 17 games in charge.
Ange Postecoglou has garnered a growing reputation for his accomplishments at Celtic, defying initial scepticism.
He secured five out of six domestic trophies during his two-year tenure with the Scottish club, endearing himself to the fans.
Although Postecoglou has limited experience coaching in European football, his management style and the brand of football played by Celtic have earned him admirers.
His commendable rebuilding efforts at Parkhead saw him overcome a Rangers side that finished 25 points clear in the 2020-21 season, securing two league titles.
Prior to his time at Celtic, he clinched two A-League championships with Brisbane Roar and led the Australian national team to the 2014 World Cup, winning the Asia Cup in 2015.
Additionally, he steered Japan's Yokohama F. Marinos to their first J League title in 15 years.
While several high-profile managers have been linked to the Tottenham job since Conte's exit, the appointment of Ange Postecoglou seems to be the most positive news.
