Okaka spent the second-half of last season on-loan at Fulham.
"Stefano is going through a tricky time," agent Domenico Scopelliti told romanews.eu.
"This week he just wanted to say that he feels in good shape and ready to play at club level as well as for the Under-21 side. He proved his form with that goal."
Okaka spent six months at Fulham last season and is looking for another spell in the Premier League.
"He is considering another experience in England, but any decision will be taken in full agreement with the club.
"We could also decide for another loan that would allow the lad to remain tied to Roma."
