Spurs lost 22 of their 38 league matches last season, accumulating only 38 points as they finished 17th – their worst finish in the Premier League.
They conceded 65 goals, with only Wolves and the relegated trio of Leicester, Ipswich and Southampton shipping more.
But Postecoglou led the club to a first major trophy in 17 years with a 1-0 win over Manchester United in the Europa League final.
The victory secured Champions League football, but it was not enough to keep Postecoglou in a job and he was sacked by the club 16 days later.
Spurs, who appointed Thomas Frank as his successor, said Postecoglou would be remembered for delivering “one of the club’s greatest moments” in becoming only the third manager to win them a European trophy.
Tottenham finished fifth in his first season in charge before he kept his promise to provide silverware in his second year.
Postecoglou was initially praised for the attacking style he implemented, but he was forced to defend himself from criticism for sticking to his principles and had to contend with a catalogue of injuries to key players.
