The Swedish international has been out since May 2025 after suffering a kneecap injury against Crystal Palace.
Initially expected to be a minor setback, the issue turned into a lengthy rehabilitation period, ruling him out for the entire season.
Concerns grew after a second operation, but Kulusevski has now revealed that the procedure proved decisive and marked a turning point in his recovery journey.
"I hear people talking: 'Will he be the same player when he returns?' No, I won't be the same player," he stated.
"I'll be much better and much stronger, smarter and better for my teammates. It's the driving force I have. It's a challenge that I haven't been able to overcome so far, since I'm not healthy.
“But it's not over yet and now is when the second game begins."
