The Ukrainian forward has struggled for first-team football in Serie A this season, but is confident that he can contribute in La Liga.
"I'm ready to play and I want to help Malaga reach as high as possible," he told reporters at a press conference.
"I'm an attacking player, I can play on the left or right flanks, or as a striker. The first days here have been really good and everyone has been very friendly.
I'm looking forward to my first training sessions. I want to play, help the team to win and get as high up the league table as we can. I feel really good here and ready to play."
It is not yet clear whether the deal involves the opportunity to make the move permanent.
