Roma have completed the signing of Internacional midfielder Jonatan Lucca.
The 18-year-old has signed a five-year deal with the Serie A club for around £550,000.
The Brazilian has now joined up with the team for their pre-season tour of Switzerland.
Roma will start the new campaign with Zdenek Zeman in charge following the departure of Luis Enrique after just one season at the Stadio Olimpico.
