Gervinho's switch was only rubberstamped last week.
“Roma is a great team with a great Coach,” he said. “Roma showed interest in me and I had no hesitation in accepting their offer.
“I want to show I can contribute to this team.
“I am not in top condition at the moment, but Garcia knows me well and knows that I still have some work to do to get fit.
“I have always had a good relationship with Garcia – he has always given me confidence, and was the first to deploy me on the wing.
“It was a real pleasure for me playing for Arsenal, but after two years of ups and downs it was time for a change."
