Petrucci will be playing for Chelsea hero Jimmy Floyd Hasselbaink, who is now coach of Antwerp.
"I'm looking forward to this experience," he told the club's official TV channel. "Hopefully I can do well and, together, we can do something good.
"Obviously, my coach was Warren Joyce and he spoke about Antwerp a lot so I know lots of things about it. From what he told me, it's a good team and crazy fans, in a good way, so I can't wait to start.
"I didn't know him [Hasselbaink] before I met him but everyone knows about him and it will be good to work with him. Hopefully, he can teach me something good and I can learn."
