Spurs needed three points to take the Premier League's top-four race to the final day but were undone by Pep Guardiola's side, who moved within touching distance of another top-flight title.
Erling Haaland's routine tap-in from Kevin De Bruyne's brilliance after 51 minutes proved a cruel blow before the City striker's stoppage-time penalty sealed a decisive three points.
It could have been a different story, though, if Stefan Ortega – on as a second-half substitute for Ederson – did not deny Heung-min Son's gilt-edged chance following Manuel Akanji's error.
The City goalkeeper denied the onrushing Spurs forward when one-on-one with the visitors 1-0 up, and Postecoglou acknowledged his side failed to seize their opportunities.
"We lost the game so it was a missed chance for three points," the frustrated Tottenham manager told Sky Sports.
"We had the opportunities and we had to punish them. It was a tight game and in the big moments we were not able to capitalise and they were.
"I thought we were in the game the whole time, even at 1-0 we had a great chance to go level.
"In the second half we were chasing the game so they got a little more space but I thought we were well in it up until that point [the second goal]."
Spurs' loss proved Aston Villa's gain as Unai Emery's side qualified for the Champions League for the first time in their history, ending a 41-year absence after last featuring in the European Cup in 1982-83.
Postecoglou found it hard to seek the immediate positives, having watched Tottenham fall short and inadvertently damage rivals Arsenal's title hopes in the process.
"We lost the game so I am disappointed," the Australian added, before responding to whether any pride could be taken.
"Not right now because we have lost. We will assess the season, still one more game to go, one more game against Sheffield United and we need to make sure we win.
"I think wherever you finish is a fair reflection of where you are at."
Tottenham will finish outside the top four for the fourth time in the last five seasons, after finishing in the Champions League spots in Mauricio Pochettino’s final four full campaigns in charge (2015-16 to 2018-19).
Postecoglou acknowledged there is still work to do to catch up with England's perennial champions City.
Asked how his side measure up to Guardiola's men, he said: Nothing earth-shattering that I didn't know before the game. We still have some work to do. We need to do some work to catch up."
