Kulusevski has joined Juve from Atalanta, having originally being signed in January.
“Cristiano is fantastic, he's very nice," Kulusevski said at a press conference. “He talks to everyone, even about things off the pitch.
“His words are like petrol, I'm lucky to play with him and I hope I can help him.
“Every day is a war, you must always be at 100 per cent. You can't come to the pitch and not be concentrated because everyone would notice immediately.
“I think I can give them energy; I want to have fun when I enter the pitch. I run a lot and I will do everything to help my team win."
“He was my idol, he opened doors in Sweden that no one had ever opened," Kulusevski added. “We talked, he called me, and it was exciting for me.
“When I was little, I never though Zlatan would call me."
