Napoli have signed midfielder Amadou Diawara from Bologna, announced President Aurelio De Laurentiis via Twitter.
President De Laurentiis confirmed the deal via Twitter with this message: “And welcome to you too, Diawara.”
However, the statement on both the Napoli and Bologna websites note it is a "definitive" transfer, without giving further details.
The 19-year-old refused to attend pre-season training with Bologna, as he tried to force a move elsewhere.
Valencia, Roma, Leicester City, Aston Villa and Juventus were among the clubs interested in the Guinean.
His ascent to Serie A was extremely rapid, joining Bologna from San Marino last summer for just €600,000.
There was a bidding war, but Diawara was determined to join Napoli and turned down more lucrative offers from abroad.
