Mattia Destro could complete his transfer to Roma on Friday after Siena and Genoa resolved his co-ownership status.
Roma have been desperate to sign the striker and sold Fabio Borini to Liverpool in order to raise funds for his swoop.
However, the capital club could do nothing until Siena and Genoa – who Roma have agreed a deal with – had firstly come to an understanding.
It is understood that the Tuscan side, for whom Destro scored 12 goals last term, have sold the player to the Marassi outfit for €7m, plus a half share in Eugenio Lamanna and the loan of Valerio Verre.
Genoa, meanwhile, have accepted €5m from Roma for the striker’s loan, with his buy-out set at a further €7m next year.
Roma will also hand over half-shares in Verre and Gianmario Piscitella to the Rossoblu.
Destro has been offered a five-year contract in the capital, worth an initial €1.5m a season. His salary will rise year on year.
