The Swedish star was the standout performer for Spurs as they secured a 2-0 victory over Nottingham Forest to put them back in touch with the Premier League's top four.
As well as teeing up Richarlison for the game's opening goal, Kulusevski wrapped up the win himself with a vicious right-footed effort to beat Matt Turner at his near post.
The 23-year-old has now scored five times in all competitions this term, as well as providing two assists for his teammates.
Those assists mean that Kulusevski has now provided 17 assists in the Premier League since his first start in the competition in February 2022.
The only players to contribute more in that time are Mohamed Salah (23), Kevin De Bruyne (22), Bukayo Saka (20) and James Maddison (19).

On his current form, Kulusevski added: "On his current form: "It cannot be better. Everything is fantastic, not only today but in these last few weeks.
"First half we had a lot of the ball we just had to stay patient. Second half they were strong, it is not easy to play at this ground with the fans' energy. We had the red card and then we had to show our character."
On providing assists: "I cannot do anymore. I just try to give my team-mates the chance to score. Richi [Richarlison] is a top striker, we give him those balls and he will score them.
