Internazionale are poised to complete the signing of Brazilian winger Mancini from Roma.
Mancini is expected to seal his switch to the San Siro for a fee of €13million (10.4million) on Monday.
The 27-year-old is set to become manager Jose Mourinho's first signing since the Portuguese took over at the club in June.
Director Gabriele Oriali told the club's official website: "We have reached an economic agreement with Roma, which will be ratified next week when the player arrives."
Mancini added: "I'm really happy it ended in this way. Inter are a great side, but I want to thank Roma for these last five years."
