“I am very happy, 2020 couldn't have started any better," the Sweden international told JTV.
“It's an important day for me, my friends, my family and for everyone who has worked with me."
On Juve coach Maurizio Sarri, Kulusevski continued: “Sarri did a fantastic job at Napoli and at Chelsea. I studied his style of play and I like it a lot, because the ball moves quickly, always with two touches at most and everyone helps each other. I want to improve and I think he will make me improve a great deal here.
“From the beginning my role was a trequartista. I had a few different coaches with Atalanta and Parma, so I changed and took a few roles. I can be a winger, last season I was a mezzala, so I can play wherever the coach wants, but I see myself as a trequartista behind the strikers."
