Adriano has arrived on a free transfer from Flamengo.
"With him [Adriano], there is already a connection, and I am certain this will help us," the 33-year-old told Roma Channel. "We know that he can win us matches all on his own.
"He knows what his objectives are, and we know our own. Together, we will do great things.
"It is still early, but we have only begun pre-season training. Both he and [Fabio] Simplicio have made a good impact on the club.
"They are two great players and above all, two great people. We will help them to settle in as best as possible, and hopefully, they can help us finish on top,"
