Kulusevski, 19, has spent the 2019-20 campaign on loan with Parma, where he has scored four goals so far, including a stunning strike in a 2-2 draw against Bologna. He will stay on loan at Parma for the rest of the season.
He joined Atalanta's youth system in 2016 and made his professional debut in January 2019.
Kulusevski was born to Macedonian parents and represented the country at under-17 level. However, he earned a full cap for Sweden in their Euro 2020 qualifying match against Faroe Islands, which means he is now tied to them.
