Kulusevski scored in the 90th minute to give Tottenham a 3-3 draw against Manchester City, the defending champions, at Etihad Stadium on Sunday.
Jack Grealish’s cameo appeared to have secured City's first Premier League victory in three matches when he scored nine minutes from time.
With Phil Foden's goal after Son Heung-min scored at both ends, Pep Guardiola's side led 2-1 at halftime. Giovani Lo Celso's superb strike made it 2-2.
With Spurs committing numerous errors, City had enough chances to win convincingly but paid the price for their wastefulness.
It was their third successive draw and there was further frustration as Rodri was booked, ruling him out of the midweek trip to Aston Villa. Grealish will also be suspended against his former club.
For Spurs, after three successive defeats and a multitude of injuries, it was a highly creditable point.
City made a positive start and threatened early on when the dangerous Jeremy Doku forced a save from goalkeeper Guglielmo Vicario.
Yet from the resulting corner the hosts were punished as Vicario palmed the ball away and it was launched long out of defence towards Son.
The Korean was quickly into his stride and could not be caught as he raced into the area and rifled a shot past Ederson to give the visitors a sixth-minute lead.
It seemed the perfect start for Spurs but the celebrations quickly turned sour for the goalscorer.
Son was wrong-footed as Julian Alvarez's free-kick into the area was glanced by Erling Haaland and could not prevent the ball ricocheting off his knee into his own net.
Spurs should have conceded again moments later but were spared by an extraordinary and uncharacteristic miss by Haaland.
The prolific Norwegian looked certain to score after Bernardo Silva seized on a loose pass and squared across the area but he somehow screwed his effort wide.
City also had some sloppy moments at the back.
Ruben Dias got back to clear after Brennan Johnson got behind the defence following another long ball and Rodri tidied up after Silva gave the ball away in a dangerous position.
Spurs survived again after Doku cut inside and smashed a shot against the crossbar but City broke through after 31 minutes.
Tottenham contributed to their own downfall after giving away position and City passed their way through, with Foden finishing off following a neat turn and lay-off by Alvarez.
Alvarez struck the base of a post with another effort and Haaland was again wasteful, this time shooting over, when Spurs once more lost possession.
Tottenham continued to live dangerously and when their attempts to play out from the back faltered again early in the second half, it took a fine save from Vicario to deny Silva.
City were to rue their profligacy as Lo Celso pulled his side level 21 minutes from time.
An Alvarez pass was intercepted on halfway and Spurs pushed forward with Son finding Lo Celso on the edge of the area. The Argentinian cut inside onto his left foot and sent a low curling shot beyond Ederson's fingertips and in off the far post.
City were jolted into action and Rodri sent a shot whistling wide before Grealish turned in from a Haaland cutback.
It seemed victory was secured but Spurs had other ideas with Kulusevski rising to power in, with what seemed to be his shoulder, from a Johnson cross.
The game ended in controversy, with Haaland fuming, after play was initially allowed to continue after the forward was fouled as he played Grealish through on goal before it was then called back.
