Pascal Boisseau, the 26-year-old's agent, has said that a move to Serie A has been a long-term ambition for his client, with Roma attempting to land the winger on two previous occasions.
He told Calciomercato.com: "Gervinho had been dreaming of Serie A for at least three years. In the summer of 2010, then-Roma director general Daniele Prade wanted him in the Capital, while the club also made a proposal last year.
"His technical characteristics are unique and because of that much appreciated by several Italian directors. He has a culture of hard work and physicality that I think will make it easy for him to settle into Serie A.
"Rudi Garcia very strongly wanted him. He spoke directly to the player and when I met with the Roma directors it didn't take long to understand this was his big opportunity."
Official confirmation that Gervinho's two-year spell with Arsenal has come to an end is expected in the next 48 hours, allowing the forward to reunite with former coach Garcia at the Olimpico.
